Design, fabrication, and testing of micro-optical components for sensors and microsystems

We report on our activities in the design, fabrication, characterization and system integration of planar micro- optical elements. Microlens arrays, gratings, diffusers, beam shapers and beam splitters have been fabricated, tested and integrated in chemical analysis systems ((mu) TAS, fluorescence detection), tracking sensors for satellites, displacement sensors, optical lightpipes, LCD projector illumination photospectrometers, neural networks and multiple channel imaging systems for photolithography. Packaging and alignment strategies for sensors and optical microsystems were investigated.
