摘要
Systems and methods for performing two-dimensional (2D) high resolution spectral-spatial mapping are described. At least one embodiment includes a spectrometer for performing two-dimensional (2D) high resolution spectral-spatial mapping comprising a Fabry-Perot component configured to receive a diffuse input beam and provide a high resolution spectral mapping of the diffuse input beam in a first direction. The spectrometer further comprises a volume hologram for increasing a spectral operating range, the volume hologram configured to perform spectral mapping in a second direction orthogonal to the first direction to increase the spectral operating range. The spectrometer further comprises a charged coupled device (CCD) configured to receive output beams, the output beams used to provide spectral analysis of the input beams.
