Abstract : A ladar transmissometer and rangefinder was built using TTL and ECL technology. Emphasis was placed on the electronic circuits and the performance of the rangefinder. The unit's computer calculates and displays the ranges of up to three targets when the ladar is used as a rangefinder; when used as a transmissometer it displays the atmospheric attenuation coefficient.
