Title: The Innovations of Gerardus Van Aller
Introduction
Gerardus Van Aller is a notable inventor based in Heerlen, Netherlands. He has made significant contributions to the field of imaging technology, holding a total of 6 patents. His work primarily focuses on advancements in image intensifier tubes and X-ray detection systems.
Latest Patents
One of his latest patents is an image intensifier tube with an entrance screen photocathode. This innovative design features a photocathode that is substantially insensitive to light wavelengths above 500 nm. The exit screen includes a phosphor layer that emits notably red light with a wavelength of at least 550 nm. This design effectively eliminates the need for a reflecting metallic layer on the phosphor layer, which has been a requirement in previous models to prevent feedback radiation.
Another significant patent is for an X-ray detector with charge pattern read-out by a TFT switching matrix. This X-ray image amplifier tube is designed with an input screen that has a photocathode and a detection screen positioned closely opposite it. The detection screen is equipped with a conversion coating that transforms the photo-electron beam generated by X-ray input image signals into a potential excursion. This design allows for high image brightness dynamics without image disruption.
