Systems and Methods for Utilizing Cylindrical Beam Volume Holograms

A method for performing spectral mapping and coded spectroscopy comprising:

• receiving input beams at a cylindrical beam volume hologram (CBVH) to generate diffracted beams in a first direction and allowing beams to pass in a second direction unaffected;
• performing a spectral-spatial mapping of the input beams in the first direction;
• focusing the input beams in the second direction to generate an output;
• and
• receiving the output at a charged coupled device (CCD), the output providing a spectrum of the input beams.

A method for performing spectral mapping and coded spectroscopy comprising:

• receiving input beams at a cylindrical beam volume hologram (CBVH) to generate diffracted beams and to provide spectral-spatial mapping of the input beams in a first direction and different mappings in a second direction;
• obtaining a Fourier transform of the diffracted beams in the first direction;
• imaging the input beams in the second direction;
• and
• receiving the output at a charged coupled device (CCD), the output providing a spectrum of the input beams.
