New kind of high-speed cinecamera with a shutter intensifier
Abstract
In order to track and measure weak, small, multiple and high speed moving targets, a new kind of high speed cinecamera with a gated intensifier has been developed. The techniques of image intensifying, laser illumination, electric shuttering and high speed photography have been used, to obtain high light-gain, good imaging quality, and long measuring distance. The system has a gated intensifier and gating circuit with an adjustable gating time of 1 to 300 microns and adjustable photography frequency of 1 to 100 frames/second. The nonlens coupling method solves the two problems of electrostatic discharge and dynamic friction between the film and the optic fiber faceplate. The resolution has been improved by using a coupling fiber optic plate with low numerical aperture.
