High-throughput snapshot spectral imaging in two dimensions

We describe demonstrations of two new techniques for snapshot pectral imaging in two dimensions. The first, based on a generalisation of the Lyot filter, we believe to be the first technique able to spectrally image in snapshot mode with modest resolution and without the need for data inversion. The second demonstration is of a biologically inspired foveal hyperspectral imager, which mitigates the data acquisition and processing bottleneck encountered in traditional hyperspectral imaging approaches.
