METHOD FOR COMBINED PHOTO REGISTRATION OF FAST PROCESSES Russian patent published in 2023 - IPC G03B39/02 

FIELD: photo camera.

SUBSTANCE: technique for high-speed photographic recording on photographic film or other light-sensitive media of multi-point images of single, fast processes, in which each point carries information about a certain stage of the process under study. The method of combined photographic recording of images of a fast-flowing process with two high-speed cameras consists in forming a light flux with an input lens, dividing it in the horizontal plane into two equal parts, one part of which is directed into the first of the cameras, and the other part of the light flux is directed through an additional reflecting mirror into the second camera, in which parts of the light fluxes through the corresponding internal lenses, rasters and unfolding mirrors, which have their own rotation speed, arrive at the corresponding stationary photographic films, while the path lengths of the divided light fluxes are set equal. In this case, the mirror of one of the cameras is rotated in the opposite direction relative to the rotation of the mirror of the other camera, after which two multipoint images of the same process with opposite scanning directions are recorded.

EFFECT: providing photographic recording of multi-point images of a single, fast-flowing process simultaneously with two high-speed cameras in opposite scanning directions.
