Now, Brandon Swartz and colleagues at Vanderbilt University and the Naval Surface Warfare Center have demonstrated broadband and large-aperture metasurface edge encoders for incoherent infrared radiation (B. T. Swartz et al., Sci. Adv. 10, eadk0024; 2024).

The low-noise optical edge detection of real-world scenes (see images) was enabled by wavefront shaping via a 24-mm aperture metasurface with a refractive lens. The metasurface was inverse-designed for effective Laplacian-based edge detection in the 7.5-to-13.5-μm long-wave infrared wavelength region.

使用非相干光进行边缘编码的超表面

现在，范德比尔特大学和海军水面作战中心的 Brandon Swartz 及其同事已经展示了用于非相干红外辐射的宽带和大孔径超表面边缘编码器（BT Swartz 等人，Sci. Adv. 10，eadk0024；2024）。

现实世界场景的低噪声光学边缘检测（参见图像）是通过带有折射透镜的 24 毫米孔径超表面进行波前整形来实现的。该超表面经过逆向设计，可在 7.5 至 13.5 μm 长波红外波长区域进行有效的基于拉普拉斯的边缘检测。
