MEMS Actuators for Optical Scanning & Imaging Applications

Dr. Ankur Jain
Senior Microsystems Technology Engineer

This  seminar  will  provide  an  overview  of  optical  MEMS (micro-electro-mechanical  systems)  scanners,  with  an  emphasis  on devices  actuated  using  electro-thermal  transduction.  These  optical scanners  have  been  packaged  within  slender  endoscopes  for  in  vivo imaging of pre-cancerous cells. Single and dual-axes micromirrors that enable optically scanning in the rotational and axial directions; as well as microlens  scanners  that  can  shift  the  image  plane  for  microscopy applications will be discussed in detail. The small size and low operating voltage  of  these  scanners  make  these  devices  ideal  for  use  in endoscopic biomedical imaging applications.

Dr.  Ankur  Jain is  a Senior  Microsystems  Technology  Engineer at Tessera MEMS Technologies in Arcadia, CA where he is working on the design  and  development  of  the  next  generation  auto-focus  camera  modules for the mobile handset market. He received the B.E. (honors) degree in electrical and electronics from the Birla Institute of Technology and Science (BITS), Pilani, India; and the M.S. and Ph.D. degrees in electrical engineering from the University of Florida, Gainesville, FL. His doctoral research involved the development of optical MEMS scanners for  endoscopic  biomedical  imaging  systems.  He  is  a  member  of  Eta Kappa Nu and Tau Beta Pi, and has contributed to over 20 technical   publications.
