    摘要: A method and apparatus for measurement of individual phases of beams from a beam steering laser array relative to a reference laser beam. The disclosed method and apparatus is based on the use of a partially reflecting ellipsoidal reflector or dual paraboloidal reflector having two focal areas to make an image of the laser array located in one of the focal areas appear at the other focal area. Illumination of this image with a phase modulated beam from a reference laser coherent with the laser array allows the application of dithering techniques to measure individual phases of beams from array. Any laser beam in the array or a separate laser coherent with the laser array can be used as a reference beam. In addition, the partially reflecting ellipsoidal reflector or dual paraboloidal reflector can provide protection for the beam steering laser array from environmental impacts or damage.

    摘要: In one aspect, a scintillation generator for simulation of aero-optical and atmospheric turbulence is described. A first deformable mirror is illuminated using collimated light from a source laser beam. In one aspect, movement of a first deformable mirror is controlled to modulate a reflected laser beam to induce wave-front phase errors onto the reflected laser beam to simulate propagation of the reflected laser beam through near-field aero-optical disturbance. In one aspect, the reflected laser beam is focused onto a second deformable mirror to form a near-field beam. In one aspect, movement of the second deformable mirror is controlled to modulate a reflection of the near-field laser beam to induce amplitude fluctuations onto the reflected near-field laser beam to simulate propagation of the reflected near-field laser beam through far-field atmospheric turbulence. The second deformable mirror is in a Fourier plane of the first deformable mirror. Other aspects are described and claimed.
