Abstract
Optical apparatus includes a Fresnel lens (), including an array of refractive bands () bordered by abrupt phase steps () of a height selected so as to focus light in different, first and second wavelength ranges from an object plane () toward an image plane () with a modulation transfer function (MTF) in excess of a predefined threshold, while focusing light in a third wavelength range, intermediate the first and second wavelength ranges, with MTF less than the predefined threshold. A display () is configured to generate, at the object plane of the Fresnel lens, an image including first and second pixel colors within the first and second wavelength ranges, respectively.
