Paper Abstract

Long path atmospheric laser transmission measurements require the precise measurement of the radiant energy of laser beams after they have been turbled by the atmosphere. This requires a detector/integrator package with very uniform response and low speckle noise. A two scatter plate device has been fabricated for use with a lmm square cryogenic infrared detector. CO2 laser measurements have been made which verify the uniformity of response and low speckle noise. Absolute accuracies of better than 1% RMS are achieved with this device. The device is augmented with a Si Diode and allows atmospheric transmission measurements to be carried out for lasers in the wavelength range of 0.6 to 11.2 microns.
