Title: Wilhelm Pfanhauser: Innovator in Solid State Exposure Measurement
Introduction
Wilhelm Pfanhauser is a notable inventor based in Munich, Germany. He has made significant contributions to the field of exposure measurement technology. His innovative work has led to the development of a unique patent that enhances the functionality of charge-coupled devices (CCDs).
Latest Patents
Pfanhauser holds a patent for a solid state exposuremeter. This invention allows a charge-coupled device to operate as an exposuremeter during normal exposure of the parallel register. The technology involves temporarily switching one of the parallel register gates between drive circuitry and a sense amplifier. During exposure to photons, the gate potentials are adjusted to store photonic generated charge under one or more phases. A designated sense gate is disconnected from the normal gate driver and connected to a high input impedance amplifier. By changing the potential on a gate adjacent to the sense gate, charge is transferred under the sense gate and back again, producing a voltage transient proportional to the total transferred charge.
