Abstract
Systems and methods for performing spectral-spatial mapping in (one and two dimensions) and coded spectroscopy are described. At least one embodiment includes a system for performing spectral-spatial mapping and coded spectroscopy comprising a cylindrical beam volume hologram (CBVH), the CBVH configured to receive input beams and generate diffracted beams in a first direction to perform spectral-spatial mapping, the CBVH further configured to allow input beams to pass in a second direction orthogonal to the first direction unaffected. The system further comprises a first lens configured to receive the diffracted beams and perform a Fourier transform on the input beams in the first direction, a second lens configured to receive the diffracted beams and focus the beams in the second direction to generate output beams, and a charged coupled device (CCD) configured to receive the outputs beams, the output beams used to provide spectral analysis of the input beams.
