We present the first realisation of simultaneous multi‐spectral fluorescence imaging using a single‐photon avalanche diode (SPAD) array, where the spectral unmixing is facilitated by a plasmonic metasurface mosaic colour filter array (CFA). A 64 × 64 pixel format silicon SPAD array is used to record...
