    Abstract: A spatial light modulator having an active and a peripheral region, wherein coherent light impinges on both regions, but due to a higher spatial frequency of pixels within the peripheral region, and due to biasing the peripheral region pixels to maximize dispersion of reflected light therefrom, a majority of light reflected from the peripheral region is directed outside of a three-dimensional target window. A spatial frequency of the pixels in the active region is selected such that maximum dispersion of reflected light from the active region is incident within the three-dimensional target window. In this way, incident light that does not reflect from the active region need not be absorbed, or blocked, but instead can be reflected, but still fails to interfere with the target window.
