Abstract
An optical system including at least one liquid crystal lens and an imaging lens module is provided. The optical system is configured to form an image of an object. The at least one liquid crystal lens and the imaging lens module is disposed on a path of light from the object. The at least one liquid crystal lens includes a first substrate, a second substrate, and a liquid crystal layer. The second substrate is opposite to the first substrate. The liquid crystal layer is disposed between the first substrate and the second substrate. An effective refractive index of each position on the liquid crystal layer is related to an voltage applied, and the at least one liquid crystal lens is configured to change an optical axis of the at least one liquid crystal lens by changing distribution of orientations of liquid crystal molecules of the liquid crystal layer.
