Abstract:
1. An optical control component, comprising: a first component beam divider/combiner disposed along a first component input optical path of an incident optical wavefront; a first component binary MEMS device M a first component binary MEMS device M phase retarder means for making L wherein an at least one M 1 1 sub array (X×Y) M1 is in an ON/OFF state and a complementary an at least one M 2 1 sub array (X×Y) M2 is in an OFF/ON state, further wherein an output wavefront propagating along a first component output optical wavefront path has a controlled modulation, wherein L 1 1 is different than L 2 1 by an amount Δ 1 L 1 L 2 , where 0<Δ 1 L 1 L 2 ≦(2n+1)λ/2, where n=0, 1, 3, . . . , so as to provide a phase shift ≦π radians.
