Abstract
Ultrasound is widely used in various applications, such as monitoring the state of structures, biomed-ical ultrasound imaging, and information (data) transmission. Ultrasonic transceivers are one of the modern communication systems, both for short-range and remote access. Indeed, the technology of the process of transmitting information using communication channels based on ultrasonic (US) vi-brations and the physical implementation of transmission using optical fiber are widely used in con-ditions of confidentiality of data processing. At the same time, the needs of wireless and wired communication demanded the development of more advanced applications (software, hardware solutions). In particular, new challenges have arisen requiring transceivers to have high frequency, wide bandwidth and compact size. Aim. Consider the “technology – opto-ultrasonic” approach used in data transmission and reception channels. This technology involves the generation of ultrasound by a pulse using the optical-acoustic effect, followed by the reception and processing of ultrasonic vibrations. Optical ultrasonic transceivers based on the photo-acoustic (US) principle of operation have great potential, in particular, to obtain the necessary: (super high) frequency of the transmitted signal; wide bandwidth (speed); ease of use as transceivers; low manufacturing cost. Materials and methods. Various methods of spectral analysis (Fourier and Wavelet) have been in-vestigated to ensure the achievement of the above goal. Results. Compared to traditional technolo-gies of information reception and transmission, optical ultrasonic transceivers provide high-frequency communication, wide bandwidth and compact size. Conclusion. The paper investigates the methods of spectral analysis (Fourier and Wavelet) and proposes, based on these studies, possi-ble options for the implementation of optical ultrasonic transceivers that can generate ultrasonic pulses with a duration on a nanosecond scale using an ultrafast laser and receive confidential data with a high degree of security. At the same time, by combining the principle of generating photo-acoustic ultrasound with the use of optical fiber, it is possible to obtain compact and inexpensive ul-trasonic transceivers.

Summary
The development of wireless high-frequency communication technology has been going on for more than 10 years, but it has not received widespread use. We propose a variant for implementing a communication channel with ultrasonic sensors, which combines the use of ultrasound and a method for creating optical pulses of a given duration This improves the efficiency of information transfer compared to standard ultrasonic techniques, while providing reduced signal energy loss and maximum control over the waveforms of the ultrasonic transmitter and data receiver [9,10,11,12]. Statement of the problem It is required to research and develop a new approach “opto-ultrasound” effective for use in data transmission and reception channels This technology involves the generation of ultrasound by a pulse due to the optical-acoustic effect.
