Title: Dirk Heydhausen: Innovator in Emissivity-Corrected Pyrometry
Introduction
Dirk Heydhausen is a notable inventor based in Aachen, Germany. He has made significant contributions to the field of pyrometry, particularly through his innovative methods that enhance temperature measurement accuracy.
Latest Patents
Dirk Heydhausen holds a patent for a "Method for emissivity-corrected pyrometry." This invention involves a substrate coated with a multilayer structure. The method includes layers of a first portion and layers of a second portion deposited on the first portion. During the deposition of at least one layer of the second portion, an optical measuring apparatus measures the emissivity and reflectance values on the broad side of the substrate. Using a previously determined correction value, the actual temperature of the substrate's broad side is calculated. This actual value is then used to control a heating apparatus, ensuring the substrate's temperature matches the target value. The correction value is determined during the deposition of the first portion, which occurs immediately before the second portion is deposited.
