A computerized video-electronic device for particle track measurements

Abstract A video-electronic device with improved speed and precision has been developped for track measurements in the volume of emulsion and AgCl-detectors, with special features: 1. precise horizontal motion of the stage, separate vertical motion of the objective, 2. high speed digital imaging of the microscopic view field with a MC 68000 microprocessor, 3. track parameter measurements, geometric and densitometric, by automatic traversing a preset vertical z-range with selection of relevant signals in every z-plane, determining lateral density profiles, mean and variance.
