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, λ) (x, y, spatial coordinates; u, v, emittance angles; λ, 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.
