Study of rotating soft knife edge wavefront sensor used in adaptive optics
The concept of a new type wavefront sensor-rotating soft knife edge wavefront sensor has been proved with Fourier optics theory. At the region of knife edge, the step function of transmittance has been replaced by gradual variation function. As results, at the pupil image plane, the modulation signal which responds both amplitude and orientation of phase gradient of the detected wavefront at pupil plane can be obtained. Experimental results are also given.
