On hologram, activating hologram with transmission mode, in Fig. 1, label 4 represents human eye.
The display element of described image display system 3 is digital hologram display element, such as: LCD display,
OLCD display screen, or other can realize the element that digital hologram shows.In order to realize augmented reality effect
Really, display element is preferably transparent digital holography display element (transparent digital holography display original set can also claim
For lucidification disposal holography display chip).Hologram image display original set in image display system is at processor
Under control, change holographic structure in real time according to display information so that can reappear virtual by coherent light illumination
Thing, makes human eye visible.Specifically employ the principle that illuminating bundle by holographic structure diffraction generate required for
Virtual display light source, this light enters human eye, and people i.e. can be seen that virtual object.This utility model image display system
The hologram image of upper display is the computed hologram picture that processor generates, can be comprehensive owing to calculating holography calculating
The amplitude of record light wave and phase place, generate the algorithm of computed hologram by regulation, it is possible to achieve is projected by thing
At distance human eye 250mm to position, infinity, therefore can realize nearly eye and show, and can realize
The regulation of the depth of field, this utility model indication depth of field refers to that virtual image is from human eye distance, i.e. imaging depth.
It addition, calculate holography to show that the angle of visual field being projected out is by digital hologram display element (spatial light modulator)

The principle that implements of this utility model hologram reproduction is:
A certain moment, green light source and blue-light source are closed, and the red light that red light source sends is coupled into
In light-conducting system 2, red light, after light-conducting system 2 decoupling, is irradiated to calculate holography aobvious in transmission mode
Showing on chip, what now transparent chips display exported is the computed hologram of red beam record thing, thus aobvious
The red light portion of image information is shown.Close at subsequent time, red light source and blue-light source, green light source
The green beam of outgoing activates the computed hologram of corresponding green glow record, thus is projected out the green of image information
Light part.In like manner, the blue light components of image information can be projected out, when computed hologram and the switching of light source
Speed can be sufficiently fast, and due to the visual persistence effect of human eye, human eye just can see that the colour of trichroism superposition
Image information.Additionally when holographic display element is transparent element, human eye can also pass through transparent display element
See real external environment, it is achieved the effect of augmented reality.
Described light-conducting system 2 can be made up of single horizontal light-conducting system, it is also possible to is by vertical guide-lighting
System and horizontal light-conducting system two parts composition.
When described light-conducting system 2 is single horizontal light-conducting system, if light-source system 1 inputs light-conducting system
Light source be not wide light source, then can have a strong impact on the visual field of near-eye display system, therefore when described light-conducting system
2 when being single horizontal light-conducting system, and described light-source system 1 is preferably designed for vertical expansion light source, such as
The array light source of multiple light sources synthesis.See Fig. 2, be light-source system 1 be a during vertical expansion light source
Planting exemplary construction, in Fig. 2, vertical expansion light source uses the combination of vertical direction array fibre and microlens array.
When described light-conducting system 2 is made up of vertical light-conducting system and horizontal light-conducting system two parts, such as Fig. 3,
In Fig. 2,21 represent vertical light-conducting system, and 22 represent horizontal light-conducting system.The illumination light of light-source system output
Bundle first passes through vertical light-conducting system 21, then is coupled into horizontal light-conducting system 22；Vertical light-conducting system 21 is used for expanding
The lighting area of exhibition light source vertical direction, horizontal light-conducting system 22 goes out light for expansion light source horizontal direction
Area, after the extension of both direction, being irradiated to the light beam on digital hologram display element is area source, more
Meet the basic theories that nearly eye shows.In this kind of structure, horizontal light-conducting system 22 is in itself and vertical guide-lighting system

There is wedge angle a in the beam spread transmission parallel flat interface of flat light-conducting system so that from coating outgoing
Beam orthogonal be incident to horizontal light-conducting system, it is therefore an objective to when light beam is in horizontal light-conducting system horizontal transport not
Can tilt due to the light beam that vertical direction angle causes, reduce the chi of the vertical direction of horizontal light-conducting system
Very little, the most also reduce digital hologram device calculates holographic complexity).
