Abstract

The present invention provides a design method of stereo microscope. Traditional optical microscope is altered into the stereo microscope to obtain two different frames of pictures, and the two frames of images enter the right and left eyes separately to form one stereo image. Unlike available stereo microscopes, such as dissecting microscope, metallographical microscope and stereoscope, the stereo microscope of the present invention has great enlargement factor.

Description

Stereo microscope

The present invention relates to microscope, stereo microscope particularly, three-dimensional film, stereotelevision glasses, optics and persistence of vision.

Existing stereo microscope, anatomical lens, stereoscope, metallographic mirror its essence is telescopical amplification application, are not real stereo microscopes, and enlargement factor is not high.

The purpose of this invention is to provide real stereo microscope, improve existing stereo microscope, enlarge the enlargement factor of space image, enlarge and use.

Solution of the present invention is: utilize microscope to become two discrepant pictures to enter images of left and right eyes respectively, and form stereoscopic vision in brain.

Accompanying drawing 1-Fig. 4 is microscopical profile, (volume shape sectional drawing).

Fig. 1, Fig. 2 are the states of same microscopical two alternate of binocular optical.

Fig. 3 is two alternate state enlarged drawings of (6) and objective table (10) among Fig. 1, Fig. 2, and solid line is Fig. 1 state, and dotted line is Fig. 2 state.

Fig. 4 is two microscopes that part is incomplete.

Embodiment below in conjunction with the description of drawings stereo microscope.

Scheme one

The inboard or the outside at the right eyepiece (1) of binocular microscope, left eyepiece (2) install shutter or liquid crystal glasses sheet (3) additional, the frequency of its left and right sides alternation switch is no less than per second 16 times, light arrived eyepiece (2) through object lens (5) lens barrels (4) when sample (6) was in Fig. 1 position, shutter (3) left side is closed the right side and is opened, and when sample (6) was in Fig. 2 position, opened in shutter (3) left side, the right side is closed, discrepant two width of cloth figure have entered images of left and right eyes respectively, because persistence of vision forms stereoeffect.

Sample (6) also is simultaneously the alternately vibration of center, the visual field with objective table (10) microslide (9) cover glass (8) around axle (7), and self-consistentency is answered at the θ angle of its vibration.

The sample vibration cooperates shutter, the switch of liquid crystal lens (3), and vibration frequency is identical, still is no less than per second 16 times.

Scheme two

Utilize the convex lens image-forming principle: the convex lens incompleteness, still can imaging can two mirrors of Fig. 4 are close, the intersection cutting discards, discarding part generally should be less than 1/2nd, two mirrors are respectively or picture and enter right and left eyes and become space image.

Two microscopes among Fig. 4 all binocular microscope discard residue behind the order, so that regulate interpupillary distance and make both sides as overlapping, its incomplete object lens (12) still can adopt the method in the scheme one, make the high speed of two incomplete object lens positions replaces with complete object lens, its frequency still is not less than per second 16 times, is equivalent to object lens and sample relative motion.

As indirect inspection, be convertible into stereotelevision, film observation.

As Direct observation, because of picture is inverted image, the picture that enters right eyepiece (13) should enter left eye, the picture that enters left eyepiece (14) should advance people's right eye to be observed, thus untenable body image, for this reason, the upright back of inverted image can be observed, the both sides lens barrel (11) that for example extends adds convex lens therein, and the inverted image that object lens (12) become is upright, the distance of microscope imaging and sample when the 4f=of these convex lens does not add these convex lens.

The light that is caused by scheme one, two weakens available cold light optical fiber lamp and replenishes, can increase reflected light for increasing stereoeffect, increase the thickness of biological sample, change the cutting method of film-making, object lens can be with common, half flat field, the multiple camera lens of flat field to be obtaining better stereoeffect, moves and can subtract a surname or without cover plate for increasing operating distance and mark sheet.Reduce the sample size, change object lens front end shape and become round platform rather than original right cylinder.

Claims (5)

1, stereo microscope comprises the shutter (3) or the liquid crystal glasses sheet (3) of eyepiece (1) (2) one sides, the support (10) of vibration sample and microscope components (11), (12) of incompleteness and make the upright lens of inverted image.

2, shutter as claimed in claim 1, liquid crystal glasses sheet (3) is characterized in that the per second switch is no less than 16 times, the inboard or the outside in eyepiece (1), (2).

3, its special sheet of vibration rack as claimed in claim 1 (10) is that vibration per second with respect to object lens (5) is no less than 16 times, and cooperates with shutter, liquid crystal glasses sheet (3).

4, the micro-or telescope parts (11) of incompleteness as claimed in claim 1, (12) is characterized in that lens barrel (11), and object lens (12) have and are no more than 1/2nd incompleteness, or two incomplete object lens (12) are made object lens.

5, the upright lens of inverted image that make as claimed in claim 1 is characterized in that coming inverted image that microscope becomes is upright.
