1. A sequencer, comprising:

  • a first modulator stage, comprising;

    a first input retarder stack for receiving and transforming the polarization of light, a first electro-optic modulator for receiving and selectively modulating the polarization of a portion of light output by the first retarder stack, and a first output retarder stack for receiving and transforming the polarization of light output by the first electro-optic modulator;

    a second modulator stage, comprising;

    a second input retarder stack for receiving and transforming the polarization of light, a second electro-optic modulator for receiving and selectively modulating the polarization of a portion of light output by the second retarder stack, and a second output retarder stack for receiving and transforming the polarization of light output by the second electro-optic modulator; and

    a third modulator stage, comprising;

    a third input retarder stack for receiving and transforming the polarization of light, a third electro-optic modulator for receiving and selectively modulating the polarization of a portion of light output by the third retarder stack, and a third output retarder stack for receiving and transforming the polarization of light output by the third electro-optic modulator;

    wherein the first, second and third modulator stages each comprise at least one compensator having retardances and orientations that increase a field-of-view of the sequencer.
