Paper Abstract

A new application of design techniques for nonimaging concentrators is presented. Variable Geometry Nonimaging Optics Devices are presented for 2D systems. These devices have a variable acceptance angle allowing for its continuous variation within a range of values. The relation between the sizes of entrance and exit apertures must then vary according to the laws of nonimaging optics. This implies a variation in the size of either the entrance or the exit aperture, resulting in two types of devices. Moveable mirrors are an integral part of the new devices discussed in this paper, with positions depending on the variable acceptance angle. These new combinations of optical and mechanical solutions, although not ideal, may represent approximation ideally.
