Systems and methods of single-shot spatial frequency modulation imaging

A method for generating an image of an object, the method comprising:

• projecting a beam of light onto a first diffraction grating;
• separating, with the first diffraction grating, wavelengths of the beam of light;
• focusing, with a first lens, light projecting from the first diffraction grating;
• altering, with a reticle, each wavelength of light focused by the first lens;
• collimating, with a second lens, the light projecting from the reticle;
• multiplexing, with a second diffraction grating, the collimated light projecting from the lens;
• and
• projecting, with a third lens, the multiplexed light onto an object plane, wherein the multiplexed light is used to generate an image of an object in the object plane.

An imaging system comprising:

• a light source, wherein the light source projects a beam of light;
• a first diffraction grating, wherein the first diffraction grating projects separated wavelengths of the beam of light projected by the light source;
• a first lens, wherein the first lens focuses the separated wavelengths projected by the first diffraction grating;
• a reticle, wherein the reticle alters each wavelength focused by the first lens;
• a second lens, wherein the second lens collimates the wavelengths altered from the reticle into a collimated beam of light;
• a second diffraction grating, wherein the second diffraction grating multiplexes the collimated beam of light projecting from the second lens;
• a third lens, wherein the third lens projects the multiplexed collimated beam of light onto an object in an object plane;
• and
• an image sensor, wherein the image sensor receives the light projected onto the object and generates an image of the object.
