Paper Abstract

A prototype optical system for compact, high-speed zooming is described. The system is enabled by a pair of MEMS deformable mirrors (DMs), and is capable of high-speed optical zoom without translation of components. We describe experiments conducted with the zoom system integrated with an optical microscope, demonstrating 2.5× zoom capability. Zoom is achieved by simultaneously adjusting focal lengths of the two DMs, which are inserted between an infinity-corrected microscope objective and a tube lens. In addition to zoom, the test system is demonstrated to be capable of automated fine focus control and adaptive aberration compensation. Image quality is measured using contrast modulation, and performance of the system is quantified.
