Abstract :
We develop an imaging system for determining depth mapping properties of three-dimensional objects by using a low-voltage-driving liquid crystal (LC) lens. The focal length can be electrically controlled without any mechanical movements. The sequential photo images without the magnification and reduction are taken by tuning a focal plane along a depth direction. The depth mapping properties can be obtained by processing an image digital filter from the sequential focal images.
