ABSTRACT:
The present invention discloses a multilayer single lens structure with zooming and focusing functions, particularly a lens structure that makes use of the special properties of crystalline grains and applying a voltage to achieve the zooming and focusing functions. The present invention comprises an object lens layer; an adjustable object lens layer, capable of adjusting its index of refraction; an imaging lens layer; and a voltage regulating device; wherein the order of arranging the object lens layer and the adjustable object lens layer is interchangeable, and these layers are connected to the imaging lens layer, and the voltage regulating device is electrically connected to the adjustable object lens layer for supplying different voltages to achieve the zooming and focusing functions.
