We report on nonlinear optical image processing, such as image addition and subtraction, using photoinduced anisotropy in amorphous As(2)S(3) thin film and propose a method for contrast reversal and edge enhancement of an image.
我们报道了利用非晶态硫化砷(As₂S₃)薄膜中的光致各向异性进行非线性光学图像处理,如图像相加和相减,并提出了一种用于图像对比度反转和边缘增强的方法。
