Description
Technical field
The invention belongs to the photoelectric measurement technical field, relate to a kind of autocollimation interferometer measuration system.
Background technology
Autocollimation method can Measuring Object the low-angle distortion, but commonly used at present its measured one dimension angular distortion or two dimension angular distortion, autocollimation method can only be measured the two dimension angular distortion at the most.
The prior art the most approaching with the present invention is now mature photoelectric auto-collimation measuring system, and its principle is made up of light source 1, diaphragm 2, Amici prism 3, objective lens 4, catoptron 5 and detector 6 as shown in Figure 1.
This photoelectric auto-collimation measuring system according to the difference of the detector of selecting for use 6, only can be surveyed the one dimension angular distortion of object, or surveys the two dimension angular distortion of object, but it can not survey the 3 D deformation of object.
Summary of the invention
In order to solve the not problem of energy measurement three-dimensional perspective distortion of background technology, the objective of the invention is to provide a kind of autocollimation interferometer measuration system that can measure the three-dimensional perspective distortion.
The autocollimation interferometer measuration system of a kind of energy measurement object dimensional angular distortion that principle of work of the present invention has been based on optical autocollimating principle and grating interference principle design.
Optical system of the present invention comprises as shown in Figure 2: first light source, diaphragm, first Amici prism, second Amici prism, the 3rd Amici prism, objective lens, catoptron, ccd detector, secondary light source, autocollimatic grating, aiming grating, ccd detector.Wherein first light source, diaphragm, first Amici prism, second Amici prism, the 3rd Amici prism, objective lens, catoptron, ccd detector constitute the autocollimation light path; Secondary light source, autocollimatic grating, the 3rd Amici prism, objective lens, catoptron, aiming grating, ccd detector constitute the grating interference light path.Wherein first light source, diaphragm, first Amici prism and second Amici prism are positioned on the optical axis I successively, and first Amici prism is parallel with the light splitting surface of second Amici prism to putting; Ccd detector, aiming grating, second Amici prism, the 3rd Amici prism, objective lens, catoptron are placed on the optical axis II successively, and optical axis II is vertical with optical axis I, and second Amici prism is on optical axis I and the optical axis II simultaneously; Secondary light source, autocollimatic grating, the 3rd Amici prism are positioned on the optical axis III successively, and the 3rd Amici prism is on optical axis II and the optical axis III simultaneously; Ccd detector is positioned at the first Amici prism reflective surface, one side and coaxial with first Amici prism.
The light that is sent by first light source passes through diaphragm, again through first Amici prism, second Amici prism, the 3rd Amici prism and objective lens, return by catoptron again, return projector passes through objective lens, the 3rd Amici prism, second Amici prism and first Amici prism again, is received by ccd detector at last.Because catoptron is fixed on the object, when object did not deform, the vertical minute surface incident of the incident ray of catoptron, so the vertical direct reflection of reflection ray were promptly still returned along original optical path, and the picture point of the diaphragm that ccd detector receives is decided to be zero point; When object has torsional deflection around Y-axis and Z axle, thereby drive the catoptron respective change, the incident ray of catoptron is not in vertical minute surface incident, therefore reflection ray tilts to return, therefore the picture point relative zero skew of the diaphragm of ccd detector reception can be measured the torsional deflection of object around Y-axis and Z axle according to side-play amount.
The light that is sent by secondary light source is through after grating, the 3rd Amici prism and the objective lens, arrive catoptron, and through mirror reflects, pass through objective lens, the 3rd Amici prism and second Amici prism again, arrive the aiming grating and interfere the generation Moire fringe, receive Moire fringe by ccd detector at last with it.When object deformed around X-axis, the width and the inclination angle of the Moire fringe that ccd detector receives changed, and can measure the torsional deflection around X-axis of object according to the variable quantity at width and inclination angle.So, this autocollimation interferometer measuration system has been finished the three-dimensional perspective deformation measurement of object.
Good effect:, solved the not problem of energy measurement three-dimensional perspective distortion of background technology because the present invention's proposition is a kind of based on autocollimation grating interference principle Measuring Object three-dimensional perspective new method of deformation; The present invention has two main optical paths in the autocollimation interferometer measuration system, be respectively autocollimation light path and grating interference light path, and autocollimation and the common light path of grating interference two light path part, and wherein this light path of autocollimation can be surveyed the two dimension angular distortion of object; Another dimension angular distortion is recorded by the grating interference light path, the present invention both can measure the two dimension angular distortion, therefore can measure one dimension angular distortion again, can finish the measurement of three-dimensional perspective distortion, and utilize its precision of distortion that grating interference records to improve with the increase of grating frequency.The present invention also is applicable to the three-dimensional perspective distortion of measuring the large volume measurand; Optical system structure of the present invention is simple, realizes easily.
