And the acquisition of information technologies to the fields of technical physics.

According to the main author. St. No. 287356 an ontic-acoustic sensor is known that contains an electrical generator: ophplot, ph-oto receiver, ultrasonic cell, and phase detector.

 (The known sensor has insufficient stability xaip aKTqp.HCTHiMH.

In order to improve the stability with the iB characteristics of the proposed sensor, a full-length phase detector and a photo receiver, whose output is connected to the control input of the generator of the electric and optical signal, is fed to the input of the optical driver, receives signals from the photo output HiOHipiieMiHJ-tKi inputs from the outputs of the HiTiHipiieMiHJ-tKi generator, which are outputted from the photoiOiHipiieMiHJ-tKi outputs.

The drawing shows a block diagram of the proposed iMOTiO sensor.

The sensor consists of IPD of an analogue-131 in the form of an ultra-13V analogue | OY, two photonions 1 and 2 and 3, connected to phase detector 4, generator 5 of electrical signals, phase detector-6, form-OUT-1 output signal of the sensor, whose inputs correspond to its shape. outputs and one of the photodetectors, such as photodetector 2, and the generator 5, which is connected to the ultrasonic cell.

The proposed sensor works as follows: m.

Sveta1a1I wave 1Ne1P10; means are recorded by photofanes, the localized areas of inipiHieMa are phase-ecens from one another in the direction of ultrasound propagation. Since the luminous flux is modulated in BpeiMiaHH and in space, the frequency of the signals from the photoresistors of the oscillator frequency is 5, i.e. the frequency of the ultrasound, and the phase is a function of the intensity of the light wave (NU on the ultrasound cell is positioned and sensitive -ivn.ikov along the spread (pa, nan1 IUntraz In at | K01voy waves.

Consequently, with the existence of a distance between the sensitive and the first polarity of the 1H: I1Ks of the optical signals IcI1, they differ from each other by an amount depending on the ratio for the UI of the ultrasound ai distance) Mei | yu " St1B (It is MI noiBepxiHOOTHMH. For example, if the equilibrium is equal to the wavelength, then the phase shift is 2.
