Paper Abstract

The PRESS optical aircraft program is designed to furnish optical data for coordinated re-entry physics measurements on targets observed in the vicinity of the downrange test site. To supplement this effort, a facility for calibrating the instruments used on the aircraft was established at Hickam AFB in Honolulu. The underlying philosophy of calibration is to avoid the separate calibrations of individual instrumental components, detectors and windows, relying instead on portable collimators which can be used outside the aircraft and which match the characteristics of the various instruments. In order to standardize the instrument calibrations, it is also necessary to make frequent measurements of the outputs of the portable collimators. The Hickam facility includes an optical laboratory wherein the spectral irradiance of portable collimators can be directly compared to a standard collimator whose spectral irradiance is known with reasonable accuracy. The elaborate equipment for performing these operations and the methods of operation will be de-scribed, as well as the accuracy achieved in calibration and the standards used.
