Aplikasi Pengenalan Tata Surya Menggunakan 3d Hologram Berbasis Android

Sistem yang ada pada saat ini, umumnya siswa mengenal tata surya hanya dari media buku yang didapatkan dari sekolah. Gambar yang ada pada buku hanya berbentuk 2D sehingga siswa sulit untuk membayangkan bentuk asli planet dan tata surya. Namun untuk mengenal tata surya akan lebih baik menggunakan sebuah alat peraga sebagai sebuah alat pendukung untuk melengkapi media pembelajaran yang sudah ada. Dengan adanya Teknologi 3D Hologram penulis ingin memanfaatkan untuk mengenalkan tata surya bagi siswa kelas 6 SD menggunakan smartphone berbasis android dengan menerapkan teknologi 3D Hologram sebagai media pembelajaran yang menarik selaras dengan perkembangan zaman, banyak sekali aplikasi edukatif namun bukan dari generasi muda yang tidak mau mempelajari tata surya tetapi adalah cara penyampaian yang harus dikemas dengan baik mengikuti perkembangan sehingga menarik banyak minat pengguna untuk mencoba yang kemudian akan berakhir dengan mempelajari isi dari yang disampaikan di aplikasi, sehingga untuk itu dibuatlah aplikasi pengenalan tata surya menggunakan 3D Hologram Piramida dengan nilai tambah fitur speech recognition yang disertakan dalam aplikasi ini, bentuk objek tidak hanya gambar namun berbentuk 3 dimensi yang dapat dilihat 360° secara horizontal sehingga objek planet terlihat lebih nyata, kelebihan dalam aplikasi ini pengguna tidak membutuhkan banyak interaksi fisik antara smartphone dan user karena telah disediakan fitur speech recognition sehingga user hanya perlu memberi perintah melalui suara. Dapat disimpulkan teknologi 3D Hologram dapat dimanfaatkan sebagai sarana pengenalan tidak hanya bagi siswa kelas 6 SD namun juga untuk masyarakat Indonesia.

HISTOGRAM (History In Hologram): Fun Learning Media to Learn Ancient Relics of Indonesia

Archaeological objects are historical relics that have important values for human life. But not every student can see and feel the atmosphere of ancient objects, because they have long been extinct or maintained their existence. The introduction of ancient objects through the media in the form of images contained in books, two-dimensional drawings and other teaching aids, this is considered ineffective because two-dimensional picture can only be seen on one side only, but by using 3D Hologram technology it is expected that in learning it can make historical lessons about ancient objects can be more interesting and enjoyable as well as helping in introducing efforts to conserve ancient objects. The results of this research are expected to be able to provide 3D Hologram technology by utilizing the principles of holographic work that is able to provide convenience for student by their own gadget.

Learning Effectiveness of 3D Hologram Animation on Primary School Learners

Integration of technology in education is changing traditional learning methods to satisfy global requirement towards Industrial Revolution (IR) 4.0. Innovative teaching methods help teachers to motivate and engage students in their learning. This study analyzed the application of three-dimensional hologram (3DH) technology for students in primary one, two and three, to find the learning effectiveness of 3D hologram technology in the classroom. Pre-test and post-test designs were adopted according to the primary school syllabus to collect data, which were analyzed statistically using the SPSS software. The results revealed that 3DH technology integration has a great effect that positively enhances the students’ learning capacity and attracts their attention. As indicated, 72% of the students had better scores in the post-test compared to the pre-test examination after watching a 3DH animation. The increased scores prove that 3DH technology can positively influence and enhance the knowledge gained during the student learning process. An illustration in the form of a 3D hologram animation was able to grab the students’ interest and capture their attention. This paper contributes to the field of education by looking at the adoption of 3DH technology, which could effectively enhance student learning quality at an early stage.

The experimental generation of Lorentz beam with sine amplitude and vortex phase modulation wavefront

The Lorentz beam with sine amplitude and vortex phase modulation wavefront is produced by employing digital hologram technology in this beam generation experiment. The high-efficiency digital holograms and the final high-quality beams generated by the spatial light modulator are obtained. By changing the topological charge number, amplitude parameter or beam order, many novel intensity distribution patterns are obtained in the experiment, such as center-symmetrical profiles, rotation symmetric profiles, a triangle with a fan hole, a square with a cross hole and a disc with round holes and so on. The experiment results show the topological charge number, amplitude parameter and beam order all have a considerable impact on the experimentally generated intensity profile. The topological charge number is equal to the number of the local intensity minimum holes under some condition. To verify the experimental results, a comparison shows that the shapes and evolution principles of the experimental results are in accord with the desired simulation focal intensity distributions. The generated beam with the tunable property benefits the tunable optical trap application, and it is convenient for a further application. The generation and calculation methods of the beam can pave the way for the related domain.

Recent advances in metasurface hologram technologies (Invited paper)

Since Leith and Upatnieks demonstrated the first optical hologram in 1964, hologram technology has attracted a great deal of interest in a wide range of optical fields owing to its potential use in future optical applications such as holographic imaging and optical data storage. Although there have been considerable efforts to develop holographic technologies using conventional optics, critical issues still hinder future development. Recently, metasurfaces composed of artificially fabricated subwavelength structures have been considered as novel holographic devices that show an unprecedented ability to control electromagnetic waves. In this review, we outline the recent progress in metasurface holography. A general introduction to several types of metasurface holography categorized based on their physics and application is provided. Then, our personal perspective on the future of this field is discussed.

Color image encryption method based on computer generated hologram and <i>θ</i> modulation

In this paper, a new method of encrypting a color image based on <i>θ</i> modulation is proposed by using the tricolor principle and computer-generated hologram (CGH) technology. The encryption process includes the <i>θ</i>-modulated three primary color components and the coding of computer-generated hologram, which is implemented in a Fresnel diffraction and spatial filtering system. Firstly, the color image modulated by the first random phase key is divided into three encryption channels by red laser, green laser, blue laser, and tricolor filters. Each channel is introduced by a transmissive amplitude-type sinusoidal grating with different directions, which is used to separate the three primary color components in the spatial spectrum plane. Secondly, the modulation results of tricolor components are superimposed together to form a compound image, and the phase truncation of the superposition result is performed to achieve the asymmetric encryption. Finally, the amplitude of the compound image is modulated by the second random phase key and is encoded into a binary real-value gray-color CGH by Roman-type coding method. Therefore, the gray-color information of the original image is completely hidden in the encrypted CGH, which is more general and deceptive in the storage and transmission process. Decryption is an inverse process of the encryption. Firstly, the encrypted CGH is placed on the input plane of the spatial filtering and Fresnel diffraction system. Secondly, the demodulation of CGH phase key and the spatial filtering based on optical filter are performed. Finally, the color plaintext image is obtained by using the correct Fresnel diffraction. The simulation results show the validity and feasibility of the proposed method. In addition, the anti-noise attack and anti-shearing attack performance of this color image encryption method are investigated. Compared with results from the three presented methods reported in the literature, our investigated results demonstrate that this method has good robustness to noise attack and shearing attack, and has obvious advantages when the attack noise density is larger. Due to the characteristics of high security and anti-noise, we believe that this color image encryption method promises to have important applications in the information transmission and multi-user authentication.

Three-dimensional/two-dimensional convertible display based on computer-generated holograms and an amplitude-modulated spatial light modulator

A three-dimensional/two-dimensional (3-D/2-D) convertible display was proposed. The display system offers 2-D images via the traditional display technology and offers 3-D images via the computer-generated hologram (CGH) technology. In this system, 2-D and 3-D images are generated from the same amplitude-modulated spatial light modulator (SLM). In the 2-D display mode, the panel displays an amplitude-modulated image and the 2-D image is projected on a polarization-dependent diffuser (PD) screen. In the 3-D display mode, the SLM panel displays CGHs to generate 3-D images. The zero-order diffraction of the amplitude-type CGH will be blocked by a spatial filter (SF), which is designed by a polarizer. Furthermore, a liquid crystal element was employed to modulate the polarization state of the reconstructed light to let the 3-D image quality not to be reduced by the PD. Finally, the proposed system can offer 2-D and 3-D images both clearly. The system suppresses the zero-order diffraction noise of the amplitude-type CGH system successfully.
