    Abstract: A compact, efficient illumination system has many advantages over conventional illuminators based upon integrating spheres. An elliptical light source/concentrator, preferably controlled by a light stabilization system using optical feedback to control the light intensity, provides high spatial uniformity of high irradiance values can be produced over sizeable areas for testing large area detector arrays. The illuminator is simpler and more economical than traditional systems and provides extended wavelength coverage potential. The illumination system is easy to maintain.

    Abstract: Apparatus and method for radiometrically calibrating an imaging sensor array using the sun as a calibration light source in an optical system of the type having an accessible real conjugate of the entrance pupil, includes a flux concentrator for concentrating the sunlight. A flux modulator modulates the intensity of the concentrated sunlight and a flux relay for relaying the intensity modulated sunlight to the real conjugate of the entrance pupil of the optical system. A flux diffuser located at the real conjugate of the entrance pupil of the optical system illuminates the imaging sensor array with diffuse intensity modulated sunlight for calibrating the imaging sensor. A radiometric calibration assembly is proposed to calibrate an imaging sensor array of an earth imaging system. The calibration assembly comprises a flux concentrator, a flux modulator, a flux relay lens and a flux diffuser located within a conjugate pupil of the earth imaging system. The flux concentrator transfers solar flux to the flux modulator, which modulates the flux to a number of controlled, deterministic levels. The flux relay lens transfers the modulated flux to the flux diffuser. The diffused flux illuminates the imaging sensor array, resulting in electrical signals that provide information to allow accurate calibration for use in imagery.

    Abstract: A high fidelity dual source solar simulator that provides a higher fidelity spectral match to the Air Mass Zero (AM0) solar spectrum and is derived from ultraviolet (UV) and visual light from a xenon arc lamp which is band pass filtered by a hot reflective mirror and slope filtered by a color glass filter, with the infrared (IR) light from a tungsten lamp which is band pass filtered by a cold reflective mirror and slope filtered by a thin film filter, so that, when the xenon and tungsten light components are combined as spectral segments, the spectra of the simulator matches both the curve shape and integral energy of the AM0 spectra while attenuating optical spikes so as to provide high fidelity over the entire AM0 spectrum.

    Abstract: A light source (12) emits radiation which is maintained at a desired intensity by use of a photodetector which views the radiation and has a fixed relationship between incident radiation and output photodetector (18) current. Intensity of the radiation is established by varying electric current applied to the source, via a feedback loop (42, 24, 22, 34), to attain a reference value of the photodetector current, the photodetector current being representative of the desired value of radiation intensity. This procedure may be performed first in an air environment with a specific optical assembly of source and photodetector to establish the reference value of photodetector current for a desired value of radiation intensity. Thereupon, the optical system may be operated in a vacuum environment, and a monitoring of the photodetector current establishes the desired value of radiation intensity. Alternatively, the source is operated at a fixed value of excitation current, and an iris (44) or other radiation attenuator is operated to produce the reference value of photodetector current.
