Abstract
The utility model relates to an optical system, particularly an optical system using a liquid crystal board as a dividing board. The utility model has the major technical proposal that the utility model comprises an objective lens system, an eye lens and the dividing board arranged between the objective lens system and the eye lens. The utility model is characterized in that the dividing board is an LCD dividing board. A translucent half-reflecting mirror is arranged between the objective lens system and the eye lens. The LCD dividing board is arranged on one side of the translucent half-reflecting mirror and is parallel to a connecting line of the objective lens system and the eye lens. A light source is arranged outside the LCD dividing board. A projection objective is arranged between the LCD dividing board and the translucent half reflecting mirror. The device can be used for changing and regulating the precision of division.
Description
Technical field
The utility model relates to a kind of optical system, refers in particular to a kind of optical system of utilizing liquid crystal board to make graticule.
Background technology
In the prior art, the graticule in the optical system is finished once production usually by explained hereafter such as photocopying, photoetching, and the differentiation precision promptly is fixed, and can not change; Because traditional graduation adjusting is regulated by physical construction and finished, its governor motion complexity needs multiple adjusting instrument, proofreaies and correct, calibrates relatively difficulty, and generally optical system user after imbalance can't proofread and correct.
Summary of the invention
The purpose of this utility model is to design a kind of optical system of utilizing liquid crystal board to make graticule, so that change and adjustment graduation precision.
Its main technical schemes comprises objective system and eyepiece, and the graticule between objective system and eyepiece, it is characterized in that graticule is a LCD liquid crystal graticule.
Between objective system and eyepiece semi-permeable and semi-reflecting mirror is set, LCD liquid crystal graticule is positioned at a side of semi-permeable and semi-reflecting mirror, and parallel with the line of objective system and eyepiece; Arranged outside light source at LCD liquid crystal graticule; Between LCD liquid crystal graticule and semi-permeable and semi-reflecting mirror, projection objective is set.
45 degree that are wired to of semi-permeable and semi-reflecting mirror and objective system and eyepiece intersect, and the intersection of semi-permeable and semi-reflecting mirror and line is passed at the center of light source; On two sides of LCD liquid crystal graticule, polaroid is set respectively.
The utility model has the advantages that with traditional optical system of utilizing explained hereafter such as photocopying, photoetching and compare, native system is owing to adopt the LCD liquid crystal board as graticule, during use, as long as by Drive and Control Circuit and corresponding software, just can set graduation pattern, graduation precision and graduation scale value as required arbitrarily, also can provide image and target image directly to compare as requested in proportion.Secondly native system is simple in structure, small and exquisite, easy to adjust, quick; Traditional graduation adjusting is regulated by physical construction and is finished, and its governor motion complexity needs multiple adjusting instrument, proofreaies and correct, calibrates relatively difficulty, and generally optical system user after imbalance can't proofread and correct; LCD liquid crystal graticule can be adjusted easily and calibrate by keyboard, mouse, and the user can be according to different occasions, own setting accuracy and graduation form, and error ratio is bigger; The graduation of LCD liquid crystal is all by circuit control, and its measurement result can show on graticule in real time, measures fast and accurate.4th, LCD liquid crystal graticule is a kind of intelligentized display system, can point out when target occurring, warn and identification automatically.5th, the LCD graticule can be input to various photos patterns in kind on the graticule by scanner, but multiple signal such as receiving video signals and computing machine output signal also.

Fig. 2 is another kind of optical system diagram.
Fig. 3 is the 3rd a kind of optical system diagram.
Embodiment
As shown in Figure 1: between objective system 2 and eyepiece 5 LCD graticule 4 is set, the LCD panel that LCD is promptly commonly used can outsourcing, on two sides of LCD graticule 4 polaroid 3 is set respectively.After connecting conventional Drive and Control Circuit 6 on the LCD graticule 4, with regard to the course of work of may command LCD. graticule 4.Among the figure 1 is target.
Also can between objective system 2 and eyepiece 5, semi-permeable and semi-reflecting mirror 7 be set, as shown in Figure 2, LCD graticule 4 is positioned at a side of semi-permeable and semi-reflecting mirror 7, and it is parallel with the line of eyepiece 5 with objective system 2, again at the arranged outside light source 8 of LCD graticule 4, wherein, semi-permeable and semi-reflecting mirror 7 intersects with 45 degree that are wired to of objective system 2 and eyepiece 5, and the intersection of semi-permeable and semi-reflecting mirror 7 and line is passed at the center of light source 8.
Also can between LCD graticule 4 and semi-permeable and semi-reflecting mirror 7, projection objective 9 be set as required.See Fig. 3.
After this device being used for the field of view meter of detection optical system visual field, can be according to of the technical requirement of every kind of tested optical instrument to the visual field, directly set differentiation precision and graduation form, adopt the field of view meter of optics graduation to compare with tradition, can be without reading and calculating, by can directly see clearly the graduation border judge whether qualified.
Traditional optical bench on the focal plane of its parallel light tube, needs the graticule of various ways, and is simple in structure with traditional optical bench comparison behind the employing LCD liquid crystal graticule, can reduce the correction work amount of multiple graticule.
