| 摘 要： | 提出一种利用BP神经网络获取平面光学元件面形偏差的方法。该方法先确定一幅干涉条纹图像测试区域中条纹弯曲量和条纹间距,然后对BP神经网络进行训练,最后获取被测平面光学元件的光圈数。通过与Zygo激光干涉仪的测量结果进行比较,发现两者的测量结果相吻合。实验结果表明,该方法不仅可以增强处理干涉条纹图像的适应性,而且可以提高测量精度。

| Abstract: | A method of obtaining the surface form deviation of the plane optical element by using BP neural network is presented. The curvatures of the interference fringes and the values of the fringe spacing of tested zones in the interferogram are determined,and the BP neural network is trained to obtain the value of light ring of the plane optical element. It is found that the test results obtained by Zygo interferometer are consistent with the test results obtained by the proposed method. Experimental results sho... |
