Head-mounted three-dimensional holographic image observation device

Abstract

The invention discloses a head-mounted three-dimensional holographic image observation device comprising an outer lens frame, an inner lens frame, a camera base, a camera, a holographic lens, a dividing bar, an outer sleeve and a headband. The inner lens frame is arranged at the rear side of the outer lens frame. The camera base is arranged at the inner lens frame; the camera is arranged on the camera base; the dividing bar is arranged at the lower side of the outer lens frame; the holographic lens is mounted between the outer lens frame and the dividing bar; the outer sleeve is arranged at the rear side of the inner lens frame; and the headband is connected to the inner lens frame inside the outer sleeve. According to the invention, a holographic lens slide way and an ordinary lens slideway are arranged on the outer lens frame and the holographic lens and the ordinary lens can be selectively installed, so that users with nearsighted and farsighted problems can watch information displayed on the holographic lens clearly. Therefore, a problem that the device is not suitable for the myopia or farsighted people is solved. The practicability is improved; and the lens is convenient todismount or replace.

Description

technical field [0001] The invention relates to the technical field of holographic projection, in particular to a head-mounted three-dimensional holographic image observation device. Background technique [0002] Holographic technology is a technology that uses the principle of interference and diffraction to record and reproduce the real three-dimensional image of an object. The first step is to use the principle of interference to record the light wave information of the object, and the object to be photographed forms a diffuse object under laser irradiation. The other part of the laser beam is used as a reference beam to shoot on the holographic film, and interferes with the object beam superposition, and converts the phase and amplitude of each point on the object light wave into a spatially varying intensity, so that the contrast and interval between the interference fringes can be used to All the information of the light wave of the object is recorded, and the film rec...

[0002] Holographic technology is a technology that uses the principle of interference and diffraction to record and reproduce the real three-dimensional image of an object. The first step is to use the principle of interference to record the light wave information of the object, and the object to be photographed forms a diffuse object under laser irradiation. The other part of the laser beam is used as a reference beam to shoot on the holographic film, and interferes with the object beam superposition, and converts the phase and amplitude of each point on the object light wave into a spatially varying intensity, so that the contrast and interval between the interference fringes can be used to All the information of the light wave of the object is recorded, and the film recording the interference fringe becomes a hologram, or a hologram, after processing procedures such as developing and fixing. The second step is to reproduce the light wave information of the object by using the principle of diffraction. As the embodiment of holographic technology, the head-mounted holographic image observation device is more and more popular with people for its portability and practicability. When the head-mounted holographic image observation device of the prior art is in use, it cannot display the lens behind the lens. Add other lenses, so that nearsighted or hyperopic users need to take off the glasses to wear, and myopic and hyperopic users cannot see the complete content displayed on the holographic lens, which affects the use
