| 摘 要： | 利用傅里叶光学理论,证明了一种新型波面传感器——旋转软刀口波面传感器的概念.在经典刀口法的刀口区,以渐变透过率代替突变透过率函数,在光瞳象面上可获得反映光瞳面位置待测波面位相梯度及位相梯度方向的调制信号.文中给出了实验结果和讨论.

| Abstract: | 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 At the region of knife edge, the step function of transmittance has been replaced by gradual variation function.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, |
