Abstract:
Image intensifiers may include a photocathode that emits photoelectrons in proportion to the rate photons impact the photocathode. The photoelectrons are multiplied using a microchannel plate that includes a plurality of microchannels. Photoelectrons are scattered by the microchannel plate when the photoelectrons strike the surface of the microchannel plate rather than enter one of the microchannels. Electron scatter within an image intensifier results in a halo or bloom around bright or luminous objects. Halo or bloom may be minimized by reducing the electron scatter within the image intensifier. Deposition of an anti-scattering layer on the surface of the microchannel plate within the image intensifier can absorb photoelectrons that fail to enter a microchannel and may thus reduce the incidence of halo or bloom.
