Paper Abstract

Programmable diffractive optics utilizing a high-resolution liquid-crystal phase modulator is demonstrated as a technique for large-range, two-dimensional aberration control. A high-resolution phase modulator system introduces modulo-2π phase compensation via discrete-step phase modulation and operates with 307,200 independently addressable elements, and total optical efficiencies of up to 93%. Near-diffraction-limited imaging and beam directing is demonstrated in a telescope system with large off-axis aberrations. Wavelength-agile and extended spectral bandwidth operation are also demonstrated.
