Abstract: FPAs on a wafer can be tested prior to dicing the wafer into individual dies. A focal plane array (FPA) can comprise an array of photodetectors, such as microbolometers, on a semiconductor substrate or die. FPAs can be manufactured on a wafer to make multiple FPAs on a single wafer that can be later diced or divided into individual FPAs. Prior to dicing the wafer, the FPAs can be tested electrically and radiometrically in bulk to characterize individual FPAs, to identify bad pixels, to identify bad chips, to calibrate individual FPAs, and the like. These test results can be used to determine acceptable FPAs and can be used to provide initial settings for imaging systems with the tested and integrated FPA.

Abstract: Operational parameters of a single-photon detector are determined with a continuous wave laser source. At a fixed trigger, a dark count probability and a series of count probabilities at different optical powers are determined. A particular optical power is selected by using a wide-range variable attenuator to attenuate the optical power of the continuous wave laser. The dark count probability and the count probabilities are determined for different trigger rates. The operational parameters include efficiency, afterpulsing constant, and detrap time. The operational parameters are computed by fitting the computed dark count probabilities and count probabilities to a user-defined relationship.

Abstract: An apparatus and methods for retrofitting known solar simulator systems to allow the exit beam to be changed in size and location without changing the other fundamental functions of the main optical elements. The solar simulator system is provided with means for de-magnifying the exit beam to provide higher power densities at the illumination plane. By adding or replacing one final optical element, the system user can change the location of the illumination plane and the size of the illumination area. This change in size can increase or decrease the power density of the exit beam.

Abstract: Measuring the polarimetric response of an optical instrument includes the steps of: emitting light along an optical axis; receiving the light through first and second polarizers; and detecting the light received through the first and second polarizers, using a filter and a detector. A first set of measurements is obtained by measuring the intensity of light received through the first and second polarizers. A second set of measurements is obtained by placing an optical instrument along the optical axis in lieu of the filter and detector; and measuring the intensity of light received through the first polarizer, after the second polarizer has been removed. A third set of measurements is obtained using the optical instrument but having the second polarizer replace the first polarizer. The optical instrument may be characterized using the first, second and third sets of measurements. The characterization is completed without having to know the extinction ratios and the transmittance parameters of the polarizers.
