ABSTRACT:
Systems and methods for increasing the quantum efficiency of a photocathode used in an intensified an intensified array detector with a photocathode, such as a charge-coupled device (ICCD) are presented. A quantum efficiency enhancement device is disposed in front of an ICCD and is configured to enable or facilitate an increase in the angle of incidence of incoming rays incident on the photocathode. The ICCD itself may be tilted to achieve an increased angle of incidence, and such tilting is preferably only in a direction in which pixel columns of the ICCD extend such that a plane of incidence of incoming light to the ICCD is perpendicular to a direction of wavelength dispersion. The quantum efficiency enhancement device may include re-imaging optics, an optical tilt compensator and optical coupler.
