Abstract
The invention discloses a stereoscopic vision magnifier system of a single light path, which comprises an optical information collecting device, a digital signal processing device and an optical information restoring device sequentially arranged along a light path, solves the problems of a traditional stereoscopic vision magnifier, has convenient use and obvious stereoscopic vision effect by freeing a user from respectively adjusting the positions and the focal lengths of a left optical system and a right optical system, and has a great coverage range of the depth of field so that the user head can move in a larger space without influencing the image quality. An amplification factor can be changed according to practical needs by electronically zooming, and the whole practical use process can be recorded and shot in real time for a user to play back and view.
Description
Technical field
The present invention relates to a kind of magnifier, be specially a kind of stereoscopic vision magnifier system of single light path.
Background technology
The stereoscopic magnifier that exists in the market all is to utilize pure optical principle, the two-way optical system is placed right and left eyes respectively before, reach the effect of amplifying object.For fear of producing the physiology of eye effect, need adjust the position and the focal length of two-way optical system respectively in use, the optical axis that makes magnifier respectively with the optical axis coincidence of right and left eyes.Along with the enlargement factor increase of magnifier, the depth of field is corresponding to be reduced, and user's head requires to remain on relatively-stationary position.And pancratic stereoscopic magnifier, optical texture is complicated, and a large amount of lens have increased the whole weight of magnifier again.These deficiencies are all brought great inconvenience to the user.
Summary of the invention
The objective of the invention is to, propose a kind of stereoscopic vision magnifier system of single light path, solve the problems referred to above that present stereoscopic magnifier exists, the user does not need to regulate respectively the position and the focal length of left and right sides optical system, and easy to use, stereoscopic result is obvious.Depth of field coverage is big, and user's head in use can move in bigger space and not influence image quality.Can pass through electronic zoom, press actual needs and change enlargement factor.Also can record a video in real time, take pictures, supply user's playback to check whole use.
The technical scheme that the present invention adopts is following:
Stereoscopic vision magnifier system of single light path comprises the optical information harvester, digital signal processing device and the optical information reduction apparatus that are provided with along the light path order.
Preferably, said optical information harvester comprises two groups of catoptrons facing each other, optical lens group and image sensor chips, and two groups of catoptrons are placed symmetrically.
Preferably, the optical axis of optical lens group overlaps with the axis of symmetry of catoptron.
Preferably, image sensor chip is vertical with optical axis, is centered close on the optical axis.
Preferably, said digital signal processing device comprises dsp chip and peripheral circuit.
Preferably, said optical information reduction apparatus comprises two groups of miniature light-emitting diode displays and free form surface formula total reflection visual optical prism.
The present invention is with respect to prior art, and its beneficial effect is that this Zoom lens system provides 63.5mm eye pupil distance, cooperates the big exit pupil diameter of 8mm, guarantees that 95% different eye pupils are suitable for apart from the crowd, and the user need not manual adjustments; Miniscope resolution is not less than 800*600; Through binocular parallax good stereoscopic result is provided; Depth of field coverage is not less than ± 25mm, and user's head in use can move in bigger space and not influence image quality; The no more than 120g of whole magnifier weight, the user wears use for a long time can not bring very big burden; Can record a video in real time and take pictures to whole use, supply user's playback to check.

Embodiment
Below in conjunction with accompanying drawing, the present invention is done further explanation.
Referring to Fig. 1, this stereoscopic vision magnifier system of single light path comprises the optical information harvester, digital signal processing device and the optical information reduction apparatus that are provided with along the light path order.The optical information harvester comprises two groups of catoptrons facing each other (1 and 3; 2 and 4), optical lens group and image sensor chip.Two groups of catoptrons are placed symmetrically.The optical axis of optical lens group overlaps with the axis of symmetry of catoptron.Image sensor chip is vertical with optical axis, is centered close on the optical axis.Optical lens 5 has fixing focal length, and the amplification of certain multiple can be arranged image, as: 2.5X, 3X, 3.5X, 4X etc.Through the reflection of two groups of catoptrons, form one group of light path after the light entering signal harvester that body surface reflects back, inject again in one group of optical lens 5.Light arrives on the image sensor chip 6 through after the lens combination, and this chip can be responded to optical signalling and convert corresponding image analoging signal into.
Digital signal processing device mainly is made up of dsp chip 7 and peripheral circuit.Image analoging signal is handled through dsp chip 7, will convert image digital signal to, and through design can realize electronic zoom to dsp software, can the image of object be carried out the amplification of certain multiple, as: 3X.When the simulating signal of image is delivered in the dsp chip, this dsp chip can about two zone passage digital-to-analog conversions the simulating signal of image is become the two-way image digital signal, and handle the back through dsp software and realize electronic zoom function.
The optical information reduction apparatus comprises two groups of miniature light-emitting diode displays 12 and free form surface formula total reflection visual optical prism 8.This optical prism 8 is a free form surface formula total reflection visual optical prism, and light channel structure is as shown in Figure 2, comprises the plane of incidence 9 on a plane, the exit facet 10 of spherical shape and the reflecting surface 11 of free form surface.The two-way image digital signal of handling through dsp chip shows on the miniature light-emitting diode display 12 before right and left eyes respectively; The light that sends from miniature light-emitting diode display incides in the prism through the plane of incidence 9; Exit facet 10 will be totally reflected on the reflecting surface 11 from the light that the plane of incidence 9 gets into prism, and reflecting surface is reflected away by exit facet at last and converges to pupil again with light reflected back exit facet 10; Just can see the enlarged image that optical prism forms from pupil, as shown in Figure 3.
