Stereoscopic Strobing of Two High-Speed Cameras
Two methods for simultaneous exposure of film in two or more high—speed framing cameras are described. In one case, the two cameras are run independently of each other but at a frequency multiple which causes overlapping exposures. In the other case, feedback control of the second (slave) camera is derived by comparing the phase and velocity relationships of the master and slave cameras. Signals for phase and velocity are derived from the shutter—open synchronization pulse generated by a rotating—shutter optical light sensor. Limitations in use are explained.
