| contents | Multispectral polarisation imaging has a broad range of applications, from biological cell imaging to agricultural remote surveying. For such applications, especially involving lightweight unmanned aerial vehicles like drones, it is necessary to have compact, single-shot, efficient optical systems.
We present a metasurface design that diffractively separates a scene into spectral and polarimetric measurements with a single optical component, operating for 532 nm and 700 nm in a single-shot imaging system. The polarisation imaging performance of the design is shown to be robust to both spectral and angular bandwidths, and multispectral polarimetry is demonstrated experimentally. |
