An optical module, comprising a first lens and a second lens, the first lens comprising a first surface and a second surface, the second lens comprising a third surface and a fourth surface, the second surface being provided adjacent to the third surface;
- the optical module further comprises a beam splitter, a first phase retarder, and a polarizing reflection element, the beam splitter is located on a side of the first surface, and the first phase retarder and the polarizing reflection element are located on a side of the second lens;
- and
- the first lens is configured to translate relative to the second lens, which satisfies:
- 0.05<2*(T1−T2)/D1<0.3, wherein T1 is a maximum distance from the second surface to the third surface, T2 is a minimum distance from the second surface to the third surface, and D1 is an optical effective aperture of the first lens.
