Title: Jon E Tegethoff: Innovator in Low Light Level Device Testing
Introduction
Jon E Tegethoff is a notable inventor based in Schaumburg, IL (US). He has made significant contributions to the field of optical technology, particularly in the development of devices that measure light intensity gain performance.
Latest Patents
Tegethoff holds a patent for a "Portable test apparatus for low light level devices." This invention relates to an apparatus designed to measure the light intensity gain performance of an image intensifier. The apparatus features a light source that illuminates the input surface of the intensifier with light of predetermined and constant intensity. A light-sensitive detector is arranged at the output of the intensifier to receive a portion of the output light produced in response to the input light. This detector provides an electrical signal that is directly related to the intensity of the output light. An indicator is coupled to the detector to show the intensifier's light intensity gain performance based on the electrical signal. Additionally, a modification of the apparatus includes a second light-sensitive detector positioned to receive a portion of the input light, providing a reference signal. A difference amplifier determines the difference between the electrical signal and the reference signal, allowing for a more accurate indication of the intensity gain performance.
