HOLOGRAPHIC METHOD OF STUDYING NON-STATIONARY PROCESSES Russian patent published in 2017 - IPC G01B9/21 G03H1/04 G02B27/52 

FIELD: physics.

SUBSTANCE: holographic method of studying non-stationary processes, in which a coherent radiation source, a collimator and the first, the second and the third beam splitters, and mirrors are used, by which three reference and one object beams are formed. In the method realisation the said three supporting beams can be obscured by screens, allowing for sequential formation of the holograms in time.

EFFECT: ensuring the possibility of studying non-stationary processes at different stages of their development, without interfering with their physicochemical phenomena, which increases the measurement accuracy of the test process parameters.
