FIELD: measurement equipment.
SUBSTANCE: piezooptical converter signal processing device comprises optically connected a light source, a polarisation-optic system comprising a photoelastic element, two photodetectors, a source of reference voltage. At the same time the outlet of each photodetector is connected to the input of the appropriate current-voltage converter, outputs of which are connected to the input of the differential amplifier and to the input of the summing amplifier. The output of the summing amplifier is connected to the input of the error signal amplifier. A reference voltage source is connected to the second input of the error signal amplifier, and a light source - to the output of the amplifier. The output of the differential amplifier is connected to the output interface.
EFFECT: expansion of a frequency band of a recorded signal, increased reliability and accuracy of measurement of deformations, increased noise immunity, miniaturization, expansion of field of application.
