摘要： Parallel laser light beams are irradiated from different positions into a telescope. Beams of laser light are incident on a secondary mirror attitude detection mirror from different locations. Laser light detectors detect each beam of laser light reflected by the secondary mirror attitude detection mirror. A first attitude calculator determines an amount of attitude variation of a secondary mirror based on a result detected by the laser light detectors. The laser light detectors detect each beam of the laser light reflected by the primary mirror and the secondary mirror after entering the telescope. A second attitude calculator determines an amount of attitude variation of the primary mirror based on a result detected by the laser light detectors and the result detected by the laser light detectors.

摘要： Embodiments of the invention are directed to integrated resonance detectors and arrays of integrated resonance detectors and to methods for making and using the integrated resonance detectors and arrays. Integrated resonance detectors comprise a substrate, a conducting mirror layer, an active layer, and a patterned conducting layer. Electromagnetic radiation is detected by transducing a specific resonance-induced field enhancement in the active layer to a detection current that is proportional to the incident irradiance.

摘要： 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.
