Ultra-thin Near Infrared camera enabled by a flat multi-level diffractive lens

Posted on 2019-11-05 - 15:30
We experimentally demonstrate a ~1 mm-thick near infrared (NIR) camera comprised of a multi-level diffractive lens coupled with a conventional monochrome image sensor. We performed careful measurements of the point-spread function, the modulation transfer function, focusing efficiency, aberrations and the field of view the camera.
