Abstract:

The Air Force Weapons Laboratory AFWLALO expressed a need to know what characteristics of reflected laser radiation could effect the operation of the Adaptive Laser Optical Techniques ALOT tracking and pointing system. Because the radiation that is used for tracking is reflected from rough surfaces, the far field intensity pattern has a complex distribution of irradiance. This complex distribution of irradiance is called speckel. A computer model to calculate and plot laser speckle patterns was developed and tested.
