ABSTRACT:
Population and profile data of transparent bodies contained within a transparent mass are obtained using a schlieren optical system in combination with a television camera and receiver. The transparent bodies, normally indistinguishable from the transparent mass by the unaided eye, are detected by the schlieren optical system and then magnified and contrasted on the television receiver. The invention is especially useful as a means for quality control in various chemical operations.
