Optical Turbulence Measurement - Investigation for Analysis of Laser Designator Spot Patterns. Phase II (Field Test). Methodology Investigation.
Abstract
This methodology investigation evaluates the feasibility of applying video instrumentation and image analysis techniques to characterize optical path turbulence for use in assessing the field performance of laser designator systems. The effort focused on adapting a (C sulon) squared path weight measurement technique, which uses a telescope mechanical slit scanner configuration for data acquisition. This effort covers the conduct of a limited field test to validate the data acquisition and data analysis process developed during Phase I of the investigation. The field test involved making (C sulon) squared measurements with the original slit scanner equipment and a video (C sulon)squared data acquisition system. Smoke was also introduced in the optical path. The amount of test data taken was limited by severe rainstorms which occurred during a normally dry season at the test site. The test results showed a correlation of 0.81 between the data collected by the two measurement systems.
