Resolution of live electrooptic imaging with a very thin (10-µm) sensor plate

Abstract

Resolution of live electrooptic imaging (LEI) having an ultimately-thinned (10-µm) electrooptic sensor plate has been evaluated experimentally and discussed theoretically. The evaluated resolution value is 30–40 µm, which is the best ever demonstrated for the LEI technique. Through its theoretical analyses, the following three resolution-limiting factors have been quantified and a guideline for resolution improvement has been discussed; (a) the image sensor pixel density, (b) the magnification and resolution of the laser optics, and (c) the electrooptic sensitive volume.
