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 of Cun Zaiing all is to utilize pure optical principle in the market, 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, the optical texture complexity, a large amount of lens have increased the weight of magnifier integral body 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, check for user's playback to whole use.
The technical solution used in the present invention is as follows:
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, described 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, described digital signal processing device comprises dsp chip and peripheral circuit.
Preferably, described 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; Provide good stereoscopic result by binocular parallax; 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, check for user's playback.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
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 be converted to corresponding image analoging signal.
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 by design can realize electronic zoom to dsp software, the image of object can 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 zones by digital-to-analog conversion 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 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 as shown in Figure 2.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 by 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 enters prism, reflecting surface is again with light reflected back exit facet 10, reflect away by exit facet at last and converge to pupil, just can see the enlarged image that optical prism forms from pupil, as shown in Figure 3.
