During my work in projects at PSI and CSEM SA I gathered a broad practical experience in the areas:
Optical design, design of plastic optics (for injection molding), optimization of plastic optical components by 3-D simulation of the injection molding process (Moldflow MPI), colorimetry, optical 3-D sensing, CMOS chip design, optical position sensing (high-resolution absolute linear and rotary encoders), non-invasive optical glucose sensing.
At Tessera and Digital Optics Corporation (DOC) I designed lenses for mobile applications, especially EDoF lenses, distorted zoom lenses, and AF lenses with MEMs focusing.
At Heptagon / ams / ams OSRAM I mainly did designs of imaging and projection lenses for mass-production in wafer-level technique targeting mobile applications.
