Abstract:

Results of the radiometric and interferometric optical measurements performed by the crew of Gemini V during the D4D7 experiment are presented. With use of a rapid-scan Michelson PbS Interferometer and two radiometer channels filtered at 2.2 microns and 4000A, measurements of earth and lunar reflected sunlight are compared to those obtained on the Gemini VII flight. Also included are detailed calibrations of the D4D7 instrumentation used on Gemini V. Author
