First Claim
Patent Images
1. A system for positioning light beams comprising:
- (a) at least one light source, each light source for generating a light beam;
(b) a set of at least two cycloidal diffractive waveplates for deviating the light beam over a predetermined angle; and
(c) a device controlling a relative geometrical positioning of said cycloidal diffractive waveplates, for varying a deflection angle of the beam.

Abstract
Pointing and positioning system of light beams and images including a plurality of cycloidal diffractive waveplates, each waveplate capable of deviating a generally broadband light beam over a predetermined angle. The lateral translation and deviation angles of the light beams are controlled by controlling the relative distance, rotational position, and the diffraction efficiency of at least one in the plurality of waveplates.
