Title: Walter Jaerisch: Innovator in Optical Imaging Systems
Introduction
Walter Jaerisch is a notable inventor based in Böblingen, Germany. He has made significant contributions to the field of optical imaging systems, holding a total of 6 patents. His work focuses on developing methods and devices that enhance the precision and accuracy of optical imaging technologies.
Latest Patents
One of his latest patents is a method and device for testing optical imaging systems. This innovation is crucial for creating microstructures that require high precision. The method involves generating two interferograms for comparison. Initially, an interferogram of an original pattern is created, followed by a second interferogram of a copy made under identical conditions. The comparison of these two interferograms provides a measure of the imaging system's accuracy. This technique is particularly useful for testing systems that produce only mirror images.
Another significant patent by Jaerisch is the method of moire-metrical testing of optical imaging systems. This method utilizes moire stripes to assess the distortion of imaging systems. It involves creating two copies of an optical grating that are illuminated simultaneously to produce a moire pattern. The original grating is transferred onto a substrate, and the imaging system copies it again with a slight rotation. The resulting moire stripes indicate any distortions present in the imaging system, providing a quantitative measure of its errors.
Career Highlights
Throughout his career, Walter Jaerisch has worked with prominent companies, including the International Business Machines Corporation (IBM). His experience in these organizations has contributed to his expertise in optical imaging technologies.
