The arrangement of the reflective glass 4 is convenient for adjusting the imaging position, thereby improving the practicability.
More specifically, the angle c between the holographic optical lens 1 and the reflective glass 4 may be 26 degrees to 18 degrees. In this embodiment, the included angle c between the holographic optical lens 1 and the reflective glass 4 is 27 degrees, the included angle b between the holographic optical lens 1 and the display screen 2 is 116 degrees, and the included angle a between the display screen 2 and the reflective mirror 3 is 55 degrees.
