Paper Abstract

In this paper, a method for improving the performance of unit infrared detector has been proposed. An experiment was carried out by putting micro-concentrator in front of the tested detector, micro-concentrators are diffractive microlens with different numerical aperture (N.A.) which were obtained by special design and fabrication. The performance has been evaluated for the coupled detector and compared with the simulation.
