  • Patent number: 5051571
    Abstract: A cascaded adaptive optics system for correction of aberrations in a light beam. The system includes a plurality of spatial light modulators (SLMs) in a cascaded arrangement to provide an adaptive optics system characterized by wide range, rapid response, and high resolution. The spatial light modulators may be identical or have characteristics that are complementary in providing a combined output that advantageously corrects for aberrations. A conventional adaptive optics system such as a deformable mirror may be used as one or more of the SLMKs. Liquid crystal light valves (LCLVs) may be advantageously used as one or more of the SLMs in the invention. A single LCLV may be cascaded with itself in a multiple-pass configuration by means of suitable reflectors.

  • Patent number: 4044247
    Abstract: This disclosure shows a technique used for obtaining high-resolution imagery at infra-red and optical wavelengths in the presence of atmospheric turbulence. The technique uses multi-channel signal processing. Squaring circuits are utilized to obtain the squared functions of the sum and difference frequencies, structured so as to avoid atmospheric turbulent effects upon received signals. This technique is suited for imaging of objects located above the turbulent boundary layer near the earth's surface.
