Abstract
A scanning system for mapping the degree of uniformity of gas flow in the cavity of a laser includes a carriage mounted for movement along a set of parallel tracks disposed along a side of the laser cavity. The carriage mounts an infrared detector in radiation receiving relationship with the laser cavity. A screw drive mechanism is drivingly coupled to the carriage for moving it in opposite directions on the tracks. Spaced windows along the side of the laser cavity allows passage of radiation from the laser cavity to the detector. Because of the alternating relationship between transmissive windows and non-transmissive plates which defined the windows, successive portions of a voltage signal generated by the detector representing separate measurements can be easily identified with successive positions of the carriage along the laser cavity, and thus with particular successive portions of the laser cavity where each measurement was taken.
