Conventional refractive optical components such as lenses and prism modifying the wavefronts rely on light propaga-tion over distances much larger than the wavelength, which makes them bulky and weighty. To address this issue, bi-nary optics was proposed in the end of 1980s. Secondary waves created by binary optical components such as holo-grams diffract in free space and interfere in the far-field to form complex optical patterns. The phase of the secondary waves is modulated through propagation delay in a discrete and planar way. However, the chromatism in diffraction and the limited field of view due to the relatively large scale of phase modulation, limit the applications of the binary optical components.
