Abstract
A planar optical array is presented that provides a selective concentration of the light incident upon the system onto a given area. Several alternative designs are analyzed and explained geometrically. The photometric calculation is presented for three different levels of approximation. A prototype of the proposed system is tested, showing good accordance with the theoretical predictions.

We are very grateful to Félix González and Diego Castillo for their help in building the prototype. We also thank Antonio Quiroga and Héctor Canabal for his assistance in the image acquisition of the synthetic image. This research was partially supported by project MAT-95-0767 of the Comisión Interministerial de Ciencia y Tecnología of Spain. This research was finished during a stay by one of the authors (J. Alda) at the Center for Research and Education in Optics and Lasers (CREOL, University of Central Florida, Orlando, Florida). This stay was supported by the Ministerio de Educación y Cultura of Spain and by a grant from CREOL.
