An implementation of one-shot compressive imaging using a diffractive optical element

We propose and demonstrate a new implementation of compressive imaging using a diffractive optical element. This method is mathematically equivalent to existing sequential methods (Takhar et al. Proc. SPIE 6065, 2006), but utilises a static optical element to produces a spatially distributed spot array. It is envisaged that this method could be used with optical metasurfaces to perform instaneous hyperspectral and polarisation-dependent compressive imaging.
