Ultra-fast adaptive optical micro-lens arrays based on stressed liquid crystals

摘要

We characterized the optical properties of a photoresist-based micro-lens using a stressed liquid crystal matrix for high-speed variation of the focal distance. We also determined the operational parameters for the adaptive optical spherical and cylindrical micro-lens arrays. The resulting optical elements feature fast response times, around 1 ms, with a focal length range of 2600-970 mu m. Published by AIP Publishing.
