Paper Abstract

Micro-optics can be used to significantly increase the effective fill factor of focal planes. This, in turn, can enhance the overall performance of an imaging system in a number of ways. In this paper, we study the efficiency of different types of micro-concentrators, considering both the imaging and non-imaging varieties. The effective fill factor of a focal plane enhanced by a micro-concentrator is shown to be a function of three parameters: the type of micro- concentrator, the difficulty of the required concentration, and the severity of diffraction effects. For typical focal plane applications, both imaging and non-imaging concentrators are capable of increasing the effective fill factor to almost 100%.
