Abstract
An optical imaging system includes a first diffractive optical element that receives a multi-wavelength beam of light and separates the received beam of light into diffractive orders. The optical imaging system also includes a second diffractive optical element that includes panels displaced along the second diffractive element in at least one direction, where each panel is positioned to receive and pass the multi-wavelength beam of one of the diffractive orders. A refractive optical element is positioned to receive multi-wavelength beams of the diffractive orders that pass through the second diffractive element, and an optical lens that receives the multi-wavelength beams of the diffractive orders that pass through the refractive element and focuses each of the multi-wavelength beams of the diffractive orders to a different location on an image plane at the same time.
