Abstract

Programmable diffractive optics utilizing a high-resolution liquid-crystal phase modulator is demonstrated as a versatile technique for wide-dynamic-range, two-dimensional wavefront control. A high-resolution phase modulator system introduces modulo-2π phase modulation and operates with 307,200 independently addressable elements, 100% fill factor and total optical efficiencies of up to 93%. Demonstrations include beam steering, large aberration compensation, and near-diffraction-limited imaging and beam directing in a telescope system with large defocus and off-axis aberrations.
