做光学设计的同行都懂，好镜头是“调”出来的，也是“等”出来的。Zemax里反复改曲率和厚度，Lumerical里扫描周期单元的相位响应，一个参数组合跑下来，工作站转一整天是常态。更别提无透镜成像的重建调参、叠层成像的扫描校正，每一步都靠手动调试和 ...

A differentiable fractional Fourier transform (FRFT) implementation with layers that can be trained end-to-end with the rest of the network. This package provides implementations of both fast ...

Abstract: Clear and reliable images are essential in areas such as medical scans, satellite imaging, and automated inspections, where even small details matter. In this paper, we present a simple but ...

Abstract: The Fast Fourier Transform is an essential algorithm of modern computational science. The highly parallel structure of the FFT allows for its efficient implementation on graphics processing ...
