Design features of a measurement facility for the prelaunch evaluation of ir space sensors are described. After a listing of the facility's major capabilities, an analysis of its internal calibration process is given. This is followed by a discussion of test beam characteristics and some performance limitations. Concepts for improvements are presented.
A novel ir measurement facility that generates a 43-cm diam collimated beam of radiant flux in a simulated exoatmospheric environment has been built and evaluated. The broadband and spectral irradiance of the beam was measured with a calibrated integral three-grating spectroradiometer. The irradiance values cover a range of 10(8), with near Planckian(More)
The characteristics of the cw neutral argon ir laser are studied using a variety of techniques. The output power enhancement effects of helium and chlorine gases are measured, and the reasons for the enhancement are determined. The gain is measured for the 2.397-microm, 2.208-microm, 2.062-microm, and 1.792-microm laser lines, using an internal cavity-loss(More)
