Abstract
In this Letter, we present a snapshot hyperspectral light field imaging system using a single camera. By integrating an unfocused light field camera with a snapshot hyperspectral imager, the image mapping spectrometer, we captured a five-dimensional (5D) ($x,y,u,v,\lambda $) ($x,y,$ spatial coordinates; $u,v,$ emittance angles; $\lambda ,$ wavelength) datacube in a single camera exposure. The corresponding volumetric image ($x,y,z$) at each wavelength is then computed through a scale-depth space transform. We demonstrated the snapshot advantage of our system by imaging the spectral-volumetric scenes in real time.
