Abstract

We develop a three-dimensional imaging system by using a low-voltage-driving liquid crystal (LC) lens for determining depth mapping properties of three-dimensional objects. The sequential photo images without the magnification and reduction are taken by electrically controlling a focal plane along a depth direction with no mechanical movements. The depth mapping properties can be obtained by processing an image digital filter from the different focal images.
