RT Journal Article T1 Planar optical array with a spatial-integration feature A1 Vázquez Molini, Daniel A1 Alda, Javier A1 Bernabeu Martínez, Eusebio AB 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.
