Abstract
A quantitative study of the focus tuning by a liquid crystal lens in an imaging system composed of a camera module and the liquid crystal lens that performs the focusing function is reported. The resolving capability of the imaging system is investigated by analyzing the image of an ISO12233 chart formed by the system. Measurements show that with the focus tuning by the liquid crystal lens, the resolving power of the system can be very close to that of the camera module.
