Abstract
An anti-dazzle imaging camera is provided that includes a photorefractive crystal that is wavelength-agnostic. The photorefractive crystal is configured to receive an optical beam. When the optical beam includes no laser, the photorefractive crystal is configured to pass the optical beam unchanged to an imaging detector. When the optical beam includes a laser, the photorefractive crystal is configured to attenuate the laser to generate a modified optical beam and to pass the modified optical beam to the imaging detector.
