Aspheric Optical Metrology Part 1: Basics of Asphere Metrology - ISO standards - PSD - Optical shape measurement principles - Calibration and other issues Part 2: Interferometric testing using null compensators (CGH) - Null test principle - CGH fabrication, CGH certification - Dynamic null compensators Part 3: Flexible Testing methods - Pointwise: Optical CMM, profilers - Sub-apertures sequential: stitching interferometry, scanning interferometry - Full-field: Tilted Wave Interferometry, sub-Nyquist, MWLI, deflectometric About Speaker Christof Pruß (ITO) - permanent scientist at ITO, University of Stuttgart. He studied physics in Stuttgart and St. Louis, USA. Since 2001 he is leading the group “Interferometry and Diffractive Optics” at ITO. Aspheric and more recently also free form testing is in the center of his research activities. This includes the design and fabrication of diffractive optical elements such as the null correctors for testing M1 and M2 of the solar telescope GREGOR, the development of absolute testing methods with computer generated holograms (CGH) as well as flexible testing methods e.g. based on adaptive optical elements such as membrane mirrors. Christof Pruss is heading the lab for diffractive optics, where new applications and fabrication technologies for diffractive optical elements are investigated. Among them are specialized metrology systems such as hybrid imaging systems for combustion analysis for car engine development, new sensor concepts for rotary encoders or polarization beam shapers for high power lasers. He is author and coauthor of some 70 publications and 10 patents on optical metrology. An example is the new method “TWI - tilted wavefront interferometry” that has recently been awarded the “AMA Innovation price” for its high potential in flexible close-toproduction aspheretesting and was finalist for the SPIE 2015 Prism Awards for Photonics Innovation.
