1. An optical system used for displaying a target image, comprising:
a light source assembly used for generating an initial image;
an optical path adjustment assembly used for transferring the initial image to the target image, comprising a first optical element and a second optical element;
a control element used for providing a first control signal to the light source assembly;
a sensing assembly used for providing a sensing signal to the control element;
a driving assembly used to drive the second optical element to move relative to the first optical element, comprising a first driving element and a second driving element disposed on a first side of the second optical element; and
a guiding assembly comprising a first guiding element disposed on a second side of the second optical element and extending along a first axis, and a second guiding element disposed on a third side of the second optical element and extending along a second axis, wherein the first side, the second side, and the third side are different;
wherein the first optical element and the second optical element are arranged in a third axis, and the first axis, the second axis, and the third axis extend in different directions;
wherein the control element provides the first control signal based on the sensing signal.
