<p>An active optical system and method for phase-shifting desired portions of an incoming optical wavefront. A first control optics assembly receives an incoming optical wavefront and adjusts that incoming optical wavefront in accordance with first desired wavelength and beam propagation parameters. A driver element produces a driver optical wavefront. A second control optics assembly receives the driver optical wavefront and adjusts that driver optical wavefront in accordance with second desired wavelength and beam propagation parameters. A combiner receives an output from the first control optics assembly and an output from the second control optics assembly. The combiner provides a combined, co-linear propagation output wavefront having an initial beam size. Spatial light modulator (SLM) addressing optics receives the combined, co-linear propagation output wavefront and produces a desired beam size for the combined, co-linear propagation output wavefront. The SLM receives the output from the SLM addressing optics and provides localized phased shifting of the resulting wavefront. SLM egressing optics receives the output of the SLM and returns the beam size of the wavefront to the initial beam size. The output of the SLM egressing element has desired portions of its phase shifted relative to the incoming optical wavefront.</p> |
