Broadband Imaging with Diffractive Waveplate Optics

摘要

Diffractive waveplate lenses, mirrors, devices, systems and methods for performing imaging over a broad spectral band in imaging systems, such as but not limited to astronomical imaging, surveillance imaging, and in communication systems, such as laser communication systems. Corrector mirrors are used with a flat diffractive wave diffractive waveplate lens so that chromatic aberrations of the diffractive waveplate lens are reduced with the imaging system.

主权项

1. An imaging system, comprising:
a diffractive waveplate objective lens for focusing input light; a set of diffractive waveplate coated mirrors, and an imaging sensor, wherein the diffractive waveplate objective lens and the set of diffractive corrector mirrors are configured such that all rays of light within an operating wavelength band incident on the diffractive waveplate objective lens are brought to the same system focal plane on the imaging sensor.
