Enhancements in radiant energy transducer systems |
摘要 |
Many applications of radiant energy transducer systems call for specific performance characteristics over predetermined fields or surfaces. Constructive occlusion utilizes diffuse reflectivity and a mask sized/positioned to occlude an active optical area, such as an aperture of a reflective cavity, to provide tailored performance characteristics. Constructive occlusion alone or in combination with other techniques enable tailoring of the performance of a radiant energy transducer system to meet requirements of specific applications. One mechanism used to further tailor performance involves a non-diffuse reflective shoulder along a peripheral section of the mask and cavity system. Another technique involves using a retro-reflective surface, for example along a portion of the periphery of the system. Another technique involves use of a reflective wall along one side of the system, to limit the field of view to angles on the opposite side of the axis of the mask and cavity configuration.
