This paper presents a measurement system based on the transmission fringe deflectometry, which is designed to facilitate the rapid attainment of the free-form lens optical parameters, including spherical power, cylindrical power, and prismatic power. In this paper, we analyze the principle of transmission fringe deflectometry. The key technology, camera calibration, and phase unwrapping techniques...Show More
