1. A short-range optical amplification module, comprising:

  • a transflective mirror and a reflective polarizing plate that are arranged sequentially from an object side to an image side, wherein;

    the transflective mirror includes a first optical surface and a second optical surface;

    the second optical surface is a transflective optical surface, and the second optical surface is for arranging adjacent to a first phase delay plate;

    the first optical surface is for arranging adjacent to a second phase delay plate; and

    a focal length of a reflection surface of the second optical surface is greater than or equal to a system focal length of the short-range optical amplification module and is less than or equal to five times the system focal length of the short-range optical amplification module, and the system focal length of the short-range optical amplification module is greater than or equal to 10 mm and is less than or equal to 35 mm.
