Optical Turbulence Measurement - Investigations for Analysis of Laser Designator Spot Patterns.
Abstract
This methodology investigation evaluates the feasibility of applying video image analysis techniques and instrumentation to characterize optical path turbulence for use in assessing the field performance of laser designator systems. The effort focused on adpating a C sub n sub 2 path weighted measurement technique developed by Dr. E. Crittenden, NPS, which uses a telescope mechanical slit scanner configuration for data acquisition. The Phase I effort presented in this report covers a theoretical analysis and empirical measurements to include a coincident path performance comparison of the scanner and a video system in a laboratory environment. Computer programs for analyzing the video data using either a real time digitizer or a digital storage oscilloscope were also developed. The results of the investigation demonstrate that the video technique can be applied to the measurement of C sub n sub 2 and a test plan to further validate the technique in a field environment is presented.
