.: Upcoming Webinars

Optical and Electrical Microsystems for Advanced Biomedical Imaging and Diagnosis
Thu, Nov 12, 2020 10:00 AM - 11:00 AM EST
Medical diagnosis heavily depends on innovative methods for biomedical imaging. New system concepts that combine miniaturized optical MEMS components, like scanning mirrors and spatial light modulators, with new methods for realization of passive micro-optics allow for a variety of different new biomedical products. This webinar with Michael Scholles, Ph.D., Head of the Fraunhofer Project Hub MEOS will describe the technical realization of those systems in more detail, as well as their biomedical applications.
