Abstract: The invention provides a beam optical axis self-stabilizing device and method based on reflection mechanical modulation. The device includes a polarized beam splitter, a quarter-wave plate, a structural reflecting element, and a driving source. The quarter-wave plate is located at an output end of the polarized beam splitter. The reflecting element is located at a side of the quarter-wave plate away from the polarized beam splitter. The driving source drives the structural reflecting element to rotate at a uniform speed with an optical axis as an axis. Incident light passes through the polarized beam splitter to obtain split light. The split light passes through the quarter-wave plate to enter the structural reflecting element. The structural reflecting element rotates so that the phase of reflected light varies with time. The reflected light is modulated by the quarter-wave plate and emitted through the polarized beam splitter, and a target beam is obtained.
