A Proposal for a High-Speed Autofocus Microscope Based on Synchronous Control of a Resonant Variable-Focus Lens and a Short-Time Exposure Camera

A method of combining an coded exposure camera and a TAG lens with a microscope has been reported as a method of measuring 3D information in micro-space. It has been shown that high-speed 3D information measurement is possible by measuring images at multiple predetermined focal points at high speed. In this study, we propose a new autofocusing method to deal with the motion blur problem by adjusting the exposure based on this high-speed 3D microscope system, and report the effectiveness of the proposed autofocusing method from the experimental results.
