Abstract: An optical system is provided, including a movable part, a fixed part, a first sensor, a second sensor, and a control unit, wherein an optical element is disposed on the movable part. The first and second sensors detect the movement of the movable part relative to the fixed part in a first dimension and a second dimension, and thus they respectively generate a first sensing value and a second sensing value. The control unit generates an error value according to the first sensing value and an error curve, and then calibrates the second sensing value according to the error value.

Abstract: An optical element driving system is provided. The optical element driving system includes an optical element driving mechanism and a control assembly. The optical element driving mechanism includes a movable portion, a fixed portion, a driving assembly, and a position-sensing assembly. The movable portion is used for connecting to an optical element. The movable portion is movable relative to the fixed portion. The movable portion is in an accommodating space in the fixed portion. The driving assembly is used for driving the movable portion to move relative to the fixed portion. The control assembly provides a driving signal to the driving assembly to control the driving assembly. The position-sensing assembly is used for detecting the movement of the movable portion relation to the fixed portion and providing a motion-sensing signal to the control assembly.
