This thesis demonstrates a proof-of-concept experimental validation of a prototype two-beam, detection 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 od the validity of the basic design. Further research of this technology is expected to support future lase/adaptive optics long range weapon applications.
