Abstract

Utilizing our real-time heterodyne interferometer, we have been able to efficiently obtain accurate optical path difference maps of objects ten meters distant. The measurements were obtained in the presence of significant optical noise sourced from air turbulence and mechanical vibrations. Problems of long pathlength interferometry are discussed and results of noise source and system accuracy measurements are presented along with an important application.
