DEVICE OF SYNCHRONISATION OF SPEED VIDEO FILMING OF VIBRATION BURNING PROCESSES Russian patent published in 2012 - IPC H04N5/04 

FIELD: measurement equipment.

SUBSTANCE: invention relates to measurement equipment and may be used, for instance, for video registration of oscillating burning zones in combustion chambers of supersonic aviation and rocket engines in their experimental research and finishing. The device for synchronisation of speed video filming of vibration burning processes, comprising a sensor of sync signals, the output of which is connected with an input of an amplitude normaliser and a comparator by a zero transition, and between the amplitude normaliser and the comparator there is a strip electric filter, with a voltage-controlled transmission frequency, a control input of which via a frequency converter into voltage is connected with an output of the comparator, which via a discrete phase changer is connected to a synchronising input of a video camera.

EFFECT: higher accuracy of video registration of vibration burning zones in chambers of burning of supersonic aviation and rocket engines.
