Abstract:
A light beam deflector adapted for deflecting a source light beam emitted from a light source, said deflector having an optical axis and comprising:(a) in physical order, an initial beam deflector and a beam deflection amplifier;(b) said initial beam deflector receiving said source light beam and emitting an initially deflected light beam at an initial deflection angle .theta..sub.0 ;(c) said initial beam deflector including at least one piezoelectric actuator for controlling said initial deflection angle .theta..sub.0 ;(d) said beam deflection amplifier having a deflection angle amplification factor A>1; and(e) said beam deflection amplifier receiving said initially deflected light beam and transmitting a fully deflected light beam at a full deflection angle .theta.=A.theta..sub.0.
