Abstract
The present invention discloses a method and equipment for realizing stereoscopic observation in dual-eye observing light path with a single object lens. The method for realizing stereoscopic observation in dual-eye observing light path with a single object lens has the technical scheme that polarizing plates with polarization direction being mutually perpendicular approximately are arranged near an aperture diaphragm or a conjugate position of dual-eye observing light paths of a common single object lens so as to divide up an aperture; besides, polarization plates with a polarization direction being approximately identical with the corresponding polarizing plates are arranged inside two light paths of a dual-eye lens so as to realize the stereoscopic observation of an object. As a result, a three-dimensional effect under a single object lens can be obtained, and a three-dimensional effect under a high power object lens can be obtained; as a consequence, the cost of a microscope is greatly reduced.
Description
The present invention relates to a kind of method of utilizing microscope to carry out the stereoscopic observation object, particularly relate to microscope and on dual-eye observing light path with single object lens, realize the method for stereoscopic observation, the invention still further relates to and utilize this method on dual-eye observing light path with single object lens, to realize the device of stereoscopic observation.
General stereomicroscope is to utilize two different observation optical paths of left and right sides order that same object is observed, but has different observation visual angles, form so-called stereoscopic angle, it is synthetic by two light paths the information of the different viewing angles of same object to be melted picture in people's brain, forms the effect of 3 D stereo.In order to gather the information of different viewing angles, general stereomicroscope just needs paired object lens, makes that microscopical cost is higher, and general biological microscope is owing to have only object lens, it is that same information source is given two eyepieces, obtains plan view image only, can not realize stereoscopic observation.
The purpose of this invention is to provide the method and apparatus of on general dual-eye observing light path with single object lens, realizing the stereoscopic observation effect, can obtain the 3-D effect under single object lens, and the 3-D effect under the high multiple object lens, to reduce the microscope cost.
In order to achieve the above object, the present invention in the method that realizes stereoscopic observation on the dual-eye observing light path with single object lens is: 1) two roughly orthogonal polarizer slices in polarization direction are installed near the aperture diaphragm at biological microscope or near its conjugate position, two polarizer slices are arranged about by the observation place, divide the aperture equally; 2) at biological microscope from the optional position of two light paths between the eyespot to the eyepiece after the beam split light path, each install one with the roughly the same checking bias slice in corresponding polarizer slice polarization direction.
The device of on dual-eye observing light path with single object lens realizing stereoscopic observation designed according to the inventive method, it mainly is made of lens group, body.Described lens group is made of object lens, eyepiece, prism group, condenser, and this lens group is installed on the body, this device also comprise two roughly orthogonal polarizer slices in polarization direction and two with the roughly the same checking bias slice in corresponding polarizer slice polarization direction; Described two polarizer slices are installed near the aperture diaphragm of biological microscope or near its conjugate position, and two polarizer slices are arranged about by the observation place, divide the aperture equally; Described checking bias slice is installed in biological microscope respectively from the optional position of two light paths between the eyespot to the eyepiece after the beam split light path.
Because the present invention is by cutting apart the aperture installing the roughly mutually vertical polarizer slice in polarization direction near the aperture diaphragm of general dual-eye observing light path with single object lens or near its conjugate position additional, and polarization direction and the roughly the same checking bias slice of polarizer slice be installed in binocular two light paths, just can realize stereoscopic observation to object, thereby, the present invention can be used for: obtain 3-D effect at single object lens binocular vision microscopically, acquisition is than the 3-D effect of the higher multiple of general stereomicroscope, but coming of new microscope and the prior biological microscope reequiped, thereby reduce microscopical cost greatly.
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is the stereographic map of the device described in the present invention;
Fig. 2 is the location drawing of the checking bias slice described in the present invention;
Fig. 3 is the location drawing of the polarizer slice described in the present invention.
As Figure 1-3, the present invention realizes that on dual-eye observing light path with single object lens the device of stereoscopic observation mainly is made of lens group 1, body 2.
Described lens group 1 is made of object lens 11, eyepiece 12, prism group 13, condenser 14, and this lens group 1 is installed on the body 2.This device also comprise two orthogonal polarizer slices 3 in polarization direction with two with the consistent checking bias slice 4 in corresponding polarizer slice 3 polarization directions; Described two polarizer slices 3 can be installed near the aperture diaphragm of biology microscope endoscope objective lens 11 or near its conjugate position, also can be installed near near or the (see figure 3) of its conjugate position of aperture diaphragm of condenser 14, two polarizer slices 3 are divided the aperture equally by arranging about the observation place; Described checking bias slice 4 is installed in biological microscope respectively from the optional position of two light paths between the eyespot to the eyepiece 12 after the beam split light path, can be installed in the top position A of eyepiece 12 that is:, also can be installed in position B or position C (see figure 2).Vertical mutually when the polarization direction of two polarizer slices 3, effect was best when promptly angle was 90 °, but also can reach purpose of the present invention under 90 ° ± 30 ° situation; When two checking bias slices 4 were in full accord with corresponding polarizer slice 3 polarization direction respectively, effect was best when promptly angle was 0 °, but also can reach purpose of the present invention under 0 ° ± 30 ° situation.
As shown in Figure 3, as long as two polarizer slices 3 are installed near the aperture diaphragm of object lens 11 or condenser 14 or can reach purpose of the present invention near its conjugate position.
Near principle of work of the present invention: 1) two roughly orthogonal polarizer slices 3 in polarization direction (polaroid) are installed the aperture diaphragm of biological microscope, utilize the logical light principle of selectivity of polarized light, make right observation optical path can only allow the optical information in aperture, the right of object lens 11 pass through, left side observation optical path can only allow the optical information in aperture, the left side of object lens 11 pass through, like this, the same with the stereomicroscope of shared big object lens, realized utilizing the polarizer slice 3 (polaroid) of particular polarization direction to cut apart the biology microscope endoscope objective lens 11 organizator visual angles in aperture; 2) method of utilizing the checking bias slice 4 (polaroid) be installed in the particular polarization direction in the observation optical path of the left and right sides respectively to observe obtains the effect of stereoscopic observation " 3 D stereo ".
