Abstract: Described are imaging systems that employ diffractive structures as focusing optics optimized to detect visual edges (e.g., slits or bars). The diffractive structures produce edge responses that are relatively insensitive to wavelength, and can thus be used to precisely measure edge position for panchromatic sources over a wide angle of view. Simple image processing can improve measurement precision. Field-angle measurements can be made without the aid of lenses, or the concomitant cost, bulk, and complexity.

Abstract translation: 描述了采用衍射结构作为优化用于检测视觉边缘（例如，狭缝或条）的聚焦光学元件的成像系统。 衍射结构产生对波长相对不敏感的边缘响应，因此可以用于在宽视角上精确测量全色光源的边缘位置。 简单的图像处理可以提高测量精度。 场角测量可以在没有镜头的帮助下进行，或伴随的成本，体积和复杂性。
