Abstract:
A variable-range viewer for use with binocular and terrestrial telescopes was devised to enable small test charts to be vi fed in the laboratory under well-controlled, realistically simulated outdoor conditions. Object distances from 2 to 20 miles are covered by 4eans of a variable magnification optical system. Contrast attenuation by the atmosphere is introduced automaticalloy as the simulated range is changed. Provision was made for presetting any desired meteorological range from 2 to 100 miles. Author
