Prototyping of Two-Beam Laser Interferometer for Measurement of Optical Turbulence Along Extended Paths
Abstract
This thesis demonstrates a proof-of-concept experimental validation of a prototype two-beam, division of wavefront laser interferometer that provides real-time measurement of the optical path difference, and subsequent phase distortion, caused by atmospheric turbulence along an extended horizontal path. Prototype's signal processing incorporates use of specialized phase comparator circuit developed by author's advisor, D.S. Davis. Photographs and results cited of the prototype receiver's output offer proof of the validity of the basic design. Further research of this technology is expected to support future laser/adaptive optics long range weapon applications.
