Abstract
Provided herein is an optical turbulence device configured for insertion between the target collimator and the sensor unit being tested, which simulates a turbulence effect. The turbulence device for imparting wavefront aberrations to a projected radiation beam includes an optical phase element for altering the optical phase of a radiation beam. The optical phase element includes a plurality of active areas disposed on a surface of the phase element. The plurality of active areas includes a plurality of variations for imparting wavefront aberrations to a radiation beam, thereby altering optical phase of the beam. The device further includes a driving mechanism coupled to the optical phase element for transitioning the optical phase element between a plurality of positions, thereby exposing a different active area of the optical phase element to the radiation beam. The optical phase element is configured to be positioned at an intermediate focal plane of an inverting a focal optical assembly.
