Photon-sorting nanopixels for multispectral & polarisation-resolved imaging

Recent years have seen staggering growth in the prevalence of digital cameras. Conventional digital cameras are designed to mimic the response of the human eye, and therefore record the intensities of three spectral channels: red, green and blue (RGB). This project aims to harness recent advances in nano-optics for the realisation of a new generation of digital cameras. Rather than performing simple colour (RGB) imaging, these will be capable of multispectral and polarisation-resolved imaging, whose richer information will be beneficial for applications from medical diagnostics to industrial quality control. These capabilities will be enabled by optical nanostructures that deflect light in a wavelength- and polarisation-dependent manner.
