Latest Patents

Schad's innovative spirit is exemplified through his most recent patents. One of his key inventions is a process for the sampling of an electric signal varying over time. In this process, an electron beam is laterally and linearly deflected and modulated in intensity according to the instantaneous amplitude of the electric signal. This technique generates a brightness-modulated bar of light on a fluorescent screen, which is sampled using a CCD line camera. The captured analog values are then digitized and processed, resulting in impressive bandwidth and resolution while allowing for averaging without consuming additional time.

Another noteworthy invention is an optoelectronic displacement sensor designed for absolute measurement of displacement in the sub-micrometer range. This sensor employs a light-emitting diode as a light source and two photodiodes arranged in a difference circuit. Displacement is measured by moving a diaphragm between the light source and the photodiodes, affecting the illumination detected by them. To enhance the illumination's uniformity, a correction filter is strategically placed in the beam path.
