CONSTRUCTION OF SINE AND COSINE HOLOGRAM OF BRAIN TUMOR IMAGE

Abstract

Optical Scanning Holography is a technique in which an image is scanned by Time Dependent Fresnel Zone Plate and its intensity information is encoded into a two dimensional hologram. This technique not only records amplitude but also the phase of the object in case of various applications such as optical remote sensing, 3D encoding and decoding, 3D TV system. Optical scanning holography is an electronic process which is flexible, programmable and also has the capability of parallel processing. It has become a powerful technique over digital holography technique as it provides a very high processing speed, good quality color appearance, better sharpness and high resolution. An optical Fourier transform technique is used for its processing. Optical scanning holography is a real time system which involves the principle of optical heterodyne scanning. This paper proposes the construction of sine and cosine hologram of biomedical image such as brain tumor by using optical scanning setup. The holograms generated by this approach will be used for detection of tumor cells when these holograms are processed further in the reconstruction stage which will visualize more information of such a malignant cells. In the present work the construction stage of the hologram with optical set up has been accomplished and the simulation results of the hologram are observed by using MATLAB tool.
