Abstract
An overview of modeling, analysis and demonstrations of optical wavefront control implemented with a reconfigurable diffractive optic is presented. This includes, analytic modeling of the wavelength-dependent diffraction efficiency and wavefront errors associated with modulo-0 optical path control and analysis of the effects of discrete-element addressing and fill factor on diffraction efficiency. More than 200 waves of 2-D wavefront control are demonstrated with a 640x480-element optical path modulator. Wavefront steering together with field-angle-dependent aberration compensation is demonstrated as a technique for acquiring extended field-of-regard mosaic images. The effects of diffraction phenomena on image quality are analyzed.
