ABSTRACT:
Population and/or profile data of bodies contained within a transparent mass are obtained using a schlieren optical system in combination with a television camera, video analyzer, analog signal comparator and digital computer. The bodies, normally indistinguishable from the transparent mass by the unaided eye, are detected by the schlieren optical system and a television camera produces a video signal which is suitably processed, by the apparatus and method described, for introducing into a digital computer. The invention is especially useful as a means for quality control in various chemical operations.
