APPARATUS FOR CHRONOGRAPHIC RECORDING OF OPTICAL RADIATION Russian patent published in 2013 - IPC G03B39/02 G04F13/02 

FIELD: physics.

SUBSTANCE: invention can be used to investigate nonrecurrent fast processes, particularly generation of optical radiation pulses with duration of about 0.2 mcs, the number of which in the investigated object can reach about 10³. The apparatus has a high-speed photochronographic recorder comprising a control panel and a photographic camera with an electromagnetic shutter, an electric motor and a mirror position sensor, a time stamp sensor comprising a modulated optical radiation source and a radiation input device. The apparatus includes an optical radiation pulse generator with a splitter, a delayed pulse former, an optical radiation sensor, an optical radiation recorder and a personal computer. The optical output of the optical radiation pulse generator is connected by the splitter to a board, having an array of optical fibres which carry optical radiation from the investigated object. The optical radiation sensor is in form of matrix-type converter for converting an optical image to an electrical signal and lies on the focal surface of the photographic camera of the high-speed photochronographic recorder.

EFFECT: reducing time interval measurement error 2-10 fold and reducing the time for processing recorded information to tens of minutes.
