ABSTRACT:
A light deflection apparatus includes a pair of mirrors in confronting relationship, one of which is fixed in position and contains a central window, in which to input a laser light beam or in which to mount a suitable light beam generating source, such a diode laser. The other mirror is movably mounted so as to permit varying the degree of tilt between the mirrors and azimuthal location of the bisecting plane of symmetry and the spacing. The apparatus is adapted to permit targeting of light beams to different objects rapidly for use in communications systems and military systems. The apparatus also is adapted to function as the light positioning element of an optical spatial modulator.
