Abstract
The radiation beam emitted by a polychromatic source of finite dimension is initially corrected in its vergency and distribution by a reflector or a system which operates according to refraction, diffraction or total inner reflection effects. The beam then strikes on an array of micro-lenses of square or rectangular shape of arbitrary cross-section which have the function to converge and divide the beam into a plurality of partial beams which may have different directions, towards a matrix of colored micro-filters or images.
