Optical Efficiency Measurements of GEODSS ETS Telescopes from July 1976 to December 1977.
Abstract
Optical efficiency measurements are reported for five telescopes used with the GEODSS Experimental Test System. The measurements were taken and the results indicate gradual decreases in the optical efficiencies of the telescopes with use. The decreases in optical efficiencies are due to dust which accumulated on the optical surfaces of the telescopes during ETS operations.
