Paper Abstract
Image intensifier tubes, as part of night vision devices, have been the primary devices for the detection and amplification
of near infrared light for night vision operations. In this paper, we demonstrate a novel all-optical night vision amplifier
device with a potential to replace the image intensifier tube in night vision goggles. This image amplifier is based on a
novel structure of semiconductor and spectrally tunable liquid crystal (LC) materials within a thin cell. The LC reacts to
near-infrared (NIR) radiation but is unaffected by visible light, allowing see-through capability including visible-wavelength
cockpit light. The technology is made very attractive by its high sensitivity, spatial resolution, and contrast
without expensive, bulky, and heavy optics or high-voltage components.
