A Depth Sensor Based on Transient Property of Liquid Crystal Lens

Abstract The property of maintaining the lens state liquid crystal (LC) during switching between positive and negative states is made use in fast acquirement multi-focus images without magnification change. A depth from focus (DFF) pipeline that can generate a low-error map an all-in-focus image proposed. scene then obtained via DFF captured images. sensor proposed this paper has advantages simple structure, low cost, long service life.
