摘要:
An optical imaging system and method including a movable pixelated filter array, a shutter mechanism to which the pixelated filter array is attached, and a controller configured to implement a data reduction algorithm. The shutter mechanism is configured to move the pixelated filter array into and out of the optical path, and the data reduction algorithm allows the controller to account for axial and/or lateral misalignment of the filter array relative to the imaging detector array or its conjugate. In certain examples, the controller is further configured to use the data reduction algorithms also to perform wavefront sensing, for example to estimate wavefront error.
