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. |
