The floating display device is made of semi-transparent semi-reflecting lens and micro- micro-prism array, for about semi-transparent semi-reflecting lens
The position of mirror symmetry generates stereo-picture, floats on stereo-picture in the air, achievees the effect that augmented reality.
Wherein, the zoom integrated imaging devices, by Gaussian imaging equation:It can obtain:It is described
Focal length of micro-lens array is f, and the spacing between described image element array and microlens array is g, the imaging surface to lenticule
The distance between array is l.The effect of the power zoom lens is between changing between image primitive array and microlens array
Away from g, so that the available clearly stereo-picture in larger field depth, to expand imaging surface between microlens array
Depth bounds.
Wherein, the effect of micro- micro-prism array is to reflect back light along incident direction in floating display device.
Wherein, the light that the floating display device issues stereo-picture is acted on by the transmission of semi-transparent semi-reflecting lens, is arrived
Up to micro- micro-prism array surface, the light that returns along former incident direction is by the reflexs of semi-transparent semi-reflecting lens, about half
The position of saturating semi-reflective mirror mirror symmetry forms the stereo-picture with the floating of the high depth of field.
It can be seen from the above technical proposal that a kind of integration imaging 3D display device with the high depth of field of the invention has
Below the utility model has the advantages that
(1) the spacing g between display screen and microlens array is changed by the zoom effect of power zoom lens, to expand
The imaging depth of big stereo-picture.
(2) available floating by transmission, the reflex of the retroreflective action of micro- micro-prism array and semi-transparent semi-reflecting lens
Empty stereo-picture, blends with actual environment, achievees the effect that augmented reality.
(3) imaging mode is real image mode, and there is no the cuttings to image primitive.
(4) integration imaging 3D display apparatus structure of the invention is simple, convenient for operation, is suitble to more people simultaneously in different angle
Viewing, will not generate visual fatigue.
