ABSTRACT:
A light radiation concentrator comprises a frame and at least two radiation concentrating facets secured therein, the facets being made in the form of holograms. The structure of the diffraction gratings of the holograms is such that the concentrating facets have a common focal spot.
A method of making a light radiation concentrator consists in using light-sensitive objects, the number of which is equal to the number of the concentrating facets. The light-sensitive objects are secured in the concentrator frame and an interference pattern produced by a collimated reference radiation beam and an object radiation beam diverging from the focal spot is recorded in a sequence on each of the light-sensitive objects. The recording is effected by causing the collimated reference beam to move in parallel with itself and by directing the object beam from the focal spot to the respective light-sensitive object.
