Optical system of the MEhLAS cathode ray tube-analyzer

An optical system of an automated device intended for processing the film data from big bubble chambers is described. The main peculiarity of the applied optical system is the use of a measuring cathode-ray tube for manual guidance of the scanning spot to the selected film regions. The optical system under consideration provides the easily variable participation of an operator in the processes of film processing, namely in-the-process visual control, aim selection, scanning and analysis of pictures
