Embodiment 1

[0071] like Image 6 As shown, in one embodiment, preferably, the display system 13 includes: a coupling-in grating 61 , a waveguide plate 62 and an out-coupling grating 63 .

[0072] Image 6 The specific optical path principle is as follows: the light emitted by the light source 511 (LED lamp) is reflected and illuminated by the polarized light splitting element 512 to illuminate the reflective silicon-based liquid crystal 52; A 4f filter system 12 composed of a lens 41, a filter 42 and a second lens 43 filters out the light of the other orders except the first order light, and collimates it into parallel light and is incident on the coupling grating 61, and the coupling grating 61 The light is coupled into the waveguide sheet 62 , the waveguide sheet 62 transmits the coupled light to the coupling-out grating 63 , and the coupling-out grating 63 couples the light transmitted to the coupling-out grating 63 out to the human eye.

Embodiment 2

[0074] like Figure 7 As shown, in one embodiment, preferably, the display system 13 includes: a mirror 71 and a holographic optical element 72 .

[0075] Figure 7 The specific optical path principle is as follows: the light emitted by the light source 511 (LED lamp) is reflected and illuminated by the polarized light splitting element 512 to illuminate the reflective silicon-based liquid crystal 52; A 4f filter system 12 composed of a lens 41, a filter 42 and a second lens 43 filters out the light of other orders except the first order light, and collimates it into parallel light and enters the reflecting mirror 71, and the reflecting mirror 71 will The light emitted from the 4f filter system 12 is reflected to the holographic optical element 72, and the holographic optical element 72 diffracts the light transmitted to the holographic optical element 72 and then enters the human eye.

Embodiment 3

[0077] like Figure 8 As shown, in one embodiment, preferably, the display system 13 includes: a reflective mirror 81 and a half mirror 82 .

[0078] Figure 8 The specific optical path principle is as follows: the light emitted by the light source 511 (LED lamp) is reflected and illuminated by the polarized light splitting element 512 to illuminate the reflective silicon-based liquid crystal 52; A 4f filter system 12 composed of a lens 41, a filter 42 and a second lens 43 filters out the light of other orders except the first order light, and collimates it into parallel light and enters the reflecting mirror 81, and the reflecting mirror 81 will The light emitted from the 4f filter system 12 is reflected to the half mirror 82 , and the half mirror 82 reflects the light transmitted to the half mirror 82 to the human eye.

[0079] Through the above embodiments, a three-dimensional display effect can be truly achieved, and there will be no conflict between focusing and converg...

Abstract

The present disclosure relates to a holographic light field three-dimensional display device and an augmented reality display device, wherein the holographic light field three-dimensional display device includes: an image processing system, a 4f filtering system, and a display system; the image processing system is used to acquire three-dimensional image, and use a holographic three-dimensional algorithm to process the three-dimensional image to obtain a three-dimensional hologram, and display the three-dimensional hologram; the 4f filtering system is used to process the three-dimensional hologram displayed by the image processing system After filtering and collimating, the light enters the display system; the display system is used to transmit the light entering the display system and couple it to human eyes. Through the technical solution, a real three-dimensional display effect is realized, and a real and comfortable augmented reality experience is brought to the user.

Description

technical field [0001] The present disclosure relates to the technical field of augmented reality display, and in particular, to a three-dimensional display device of a holographic light field and an augmented reality display device. Background technique [0002] Augmented reality technology, referred to as AR, is a new technology that "seamlessly" integrates real world information and virtual world information. Technology, simulation and then superimposition, applying virtual information to the real world, perceived by human senses, so as to achieve a sensory experience beyond reality, real environment and virtual objects are superimposed on the same screen or space in real time. This technology not only displays real-world information, but also displays virtual information at the same time, and the two kinds of information complement and superimpose each other. In visual augmented reality, the user uses a head-mounted display to combine the real world with computer graphi...
