Purpose of the development: The device is designed to control the surface topography and the positioning accuracy of the observed objects.

Recommended application field: Measurement of the photorefractive gain. Measurement based photorefractive gain on the period and the angle of rotation of the crystal.

Technical characteristic: The laser wavelength ...... ...................................... 1,064- 1,32mkm. Measurement accuracy f photorefractive exponential factor D ............... 1%. Observation time .............................. 15 ns. Availability of software and interface.

Advantages over analogues: - flood dynamic grating in the region of weak absorption of laser radiation; - a wide range of temporary creation of holographic gratings in the crystal (from 20 ns to 1 s); - the ability to record the results on a CCD camera; - programmable accumulation and processing of results.

The development stage readiness: Tested experimental exploitation order
