The invention provides a virtual
display device, comprising a fixing portion, a protection portion, and a virtual portion. The protection portion is sleeved on an
eyepiece end of a sighting
telescope. The fixing portion fixes the protection portion and the virtual portion on the
eyepiece end. The virtual portion comprises a virtual
assembly, a display screen, and a housing. The display screen and the virtual
assembly are arranged on a housing. Light beams emitted by the display screen is zoomed and shifted through the virtual
assembly, and the light beams emitted by the display screen and light beams of an
eyepiece image close to an eye-relief of the sighting
telescope, so human eyes can clearly see a target in the eyepiece and contents displayed by the display screen. The virtual assembly of the virtual
display device is used to
zoom and shift light beams emitted by the display screen, and the light beams emitted by the display screen and light beams of the eyepiece image close to the eye-relief of the sighting
telescope, so human eyes can clearly see a target in the eyepiece and contents displayed by the display screen. Thus, a user can obtain important shooting information while aiming at a target, so as to greatly improve shooting effect.
