The report summarizes technical details of work performed at the Ohio State University ElectroScience Laboratory during the period January 8, 1971 to July 8, 1971. Progress is reported on the design, construction, and testing of apparatus and computer software for an experiment on atmospheric imaging and image reconstruction at 10.6 microns. The initial experiment involves recording, in digital format, the atmospherically degraded images of a pair of point sources and is to be applied later to images received from laser illuminated real objects. Both experimetnal equipment data processing for image reconstruction are discussed. Preliminary data obtained by imaging an atmospherically degraded laser beam during recent tests at the RADC Verona PATS test site are presented. An analysis of errors resulting from tape drop-out during digital recording using a serial Miller Code technique is presented for both linear and logarithmic processing of the analog image data prior to recording. It is shown that linear processing is generally superior for the present digital system and hence is recommended.
