Night vision system with microchannel plate for electrode contact
A recently granted patent (Publication Number: US11948786B2) discloses a novel night vision system that includes an image intensifier tube with a unique microchannel plate design. The system comprises a photocathode, a phosphor-covered anode, and a microchannel plate with funnel-shaped channel openings. These channel openings have a specific channel bias angle and are designed to draw first strike electrons produced from the photocathode to enhance image quality. The microchannel plate also features a shaded side with contact metal to facilitate the radial movement of electrons.
Furthermore, the patent details the configuration of the channel openings, the role of the contact metal in generating an electric field, and the specific design parameters such as the decreasing diameter of the funnel-shaped openings. The system aims to optimize the efficiency of electron movement within the microchannel plate to improve the overall performance of the night vision device. With claims covering various aspects of the system, including the positioning of the photocathode, the absence of contact metal on the second side of the channel openings, and the circumferential distribution of the contact metal, the patent highlights the innovative design elements that set this night vision system apart from existing technologies.
