Title: The Innovative Contributions of Daniel D. Duggan
Introduction
Daniel D. Duggan is a notable inventor based in Roanoke, VA (US). He has made significant contributions to the field of imaging technology, holding a total of 4 patents. His work focuses on enhancing the performance and functionality of image intensifier tubes and fiber optic phosphor screens.
Latest Patents
One of Duggan's latest patents is for a conductive coating for an image intensifier tube microchannel plate. This innovative design addresses the issue of accumulated electrons that can degrade the resolution of the image intensifier tube. The conductive coating is applied to the insulating surface of the microchannel plate and is formed from the evaporation of cathode sublimation products, including barium, nickel, and tungsten.
Another significant patent is for a pseudo-intagliated fiber optic phosphor screen and method. This invention involves a fiber optic phosphor screen made of an optical fiber bundle, where individual fibers are arranged in parallel. The internal surface of the screen features phosphor islands that are bonded only to the core portions of the fibers, creating a pseudo-intagliated phosphor layer. A reflective layer is then coated over the phosphor islands, enhancing the screen's performance.
