Description
Technical field
The utility model relates to a kind of auto-collimator optical system.
Background technology
Existing auto-collimating optical system is referring to accompanying drawing 1, and it comprises that principal goods mirror 1, Amici prism 2, focusing lens 3, Amici prism 4, eyepiece 6, graticule 7 and slit illumination mirror group 5 and autocollimation receive mirror group 8.Wherein Amici prism is an optical element that plays transmission and reflection double action, and its transmission part and principal goods mirror 1, focusing lens 3 and graticule 7 and eyepiece 6 are formed telescope optical system; Its reflecting part is used for linking up slit illumination mirror group 5 and autocollimation receives mirror group 8, forms three coaxial systems.The light that slit illumination mirror group 5 is sent is radiated on the object reflector former road by Amici prism 4, focusing lens 3, Amici prism 2 and principal goods mirror 1 and returns, wherein a part enters autocollimation by Amici prism 2 and receives mirror group 8, and another part is imaged on the graticule 7 for visualization through focusing lens 3 and Amici prism 4.The shortcoming that prior art exists is: focusing lens 3 is between Amici prism 2 and 4, and slit illumination mirror group 5 is in conjugate position regularly with graticule 7.Have only when focusing lens 3 is focused to the position, infinite distance, photelectric receiver 9, slit illumination mirror group 5, graticule 7 threes just have conjugate relation.The characteristics of this structure have determined under the autocollimation state, focus to the process of infinite distance from limited distance when focusing lens 3, twice slit image can occur on the graticule 7.One is telescope focusing during to the infinite distance, the slit image that occurs on the graticule 7; Another is when catoptron is seen in the telescope focusing clearly, a slit image that occurs in the visual field, this slit image is owing to only have conjugate relation and do not have conjugate relation with photelectric receiver 9 with graticule 7, so do not have slit image on the photelectric receiver 9, this picture only exists on visual graticule 7, is the autocollimation picture of a falseness.Ghost image hereto, photelectric receiver 9 does not have response, when remote alignment measurement, causes photelectric receiver 9 not receive the illusion of light signal easily, forms maloperation; And can there be certain reset error in the process that focusing lens 3 moves forward and backward, causes the uncertain of photoelectricity zero-bit.
The utility model content
The utility model has solved and has easily observed false technical matters from calibration signal in the background technology.
Technical solution of the present utility model is:
A kind of auto-collimator optical system, comprise the auto-collimating optical system that constitutes by principal goods mirror 1, Amici prism 2 and 4, slit illumination mirror group 5 and photelectric receiver 9, the telescopic optical system of forming by Amici prism 2 and 4, principal goods mirror 1, focusing lens 3 and graticule 7 and eyepiece 6, described auto-collimating optical system and telescopic optical system are formed three coaxial construction, its special character is: described slit illumination mirror group 5 is arranged in the reflected light path of Amici prism 4, and is located on the focal plane of principal goods mirror 1; Described Amici prism 2 and Amici prism 4 are arranged between principal goods mirror 1 and the focusing lens 3; Described graticule 7 is positioned on the focal plane of the combined objective that principal goods mirror 1 and focusing lens 3 form; Described eyepiece 6 is positioned at after the graticule 7.
In the reflected light path that above-mentioned principal goods mirror 1 and Amici prism 2 constitute autocollimation can be set and receive mirror group 8; 9 of photelectric receivers are positioned on the focal plane of autocollimation reception mirror group 8.
The opposite side that above-mentioned Amici prism 4 is relative with slit illumination mirror group 5 positions is provided with light-emitting device 10.
Above-mentioned light-emitting device 10 is advisable to adopt light emitting diode, also can adopt incandescent lamp etc.
The utlity model has following advantage:
1. Amici prism 4 is adjusted between principal goods mirror 1 and the focusing lens 3 by focusing lens 3 afterwards, to be in conjugate position regularly between the slit of guaranteeing auto-collimating optical system and the photelectric receiver, no matter whether telescope aims at the infinite distance, photelectric receiver all can receive the autocollimation signal, promptly need be with the collimation telescope infinite distance before the autocollimation angle measurement;
2. utilize 10 pairs of graticules 7 of light-emitting device to throw light on, light has been guaranteed graticule 7 illuminations evenly after focusing lens 3 is dispersed;
3. guaranteed focusing lens 3 in the middle of the process that moves forward and backward, on visual graticule 7, can only obtain an autocollimation picture clearly, and focusing lens 3 move forward and backward the sharpness that does not influence autocollimation picture on the photelectric receiver;
4. rational in infrastructure, self-collimation angle measuring system and telescopic system are separate, and be easy to use.
