Abstract
The invention discloses an automatic glass stress detector, comprising a polarizer, an analyzer and a detecting eyepiece, wherein the polarizer is arranged on the upper surface of a base; a support table is also arranged above the base; the analyzer can be arranged on the support table in a manual rotation manner; the detecting eyepiece is arranged above the support table in an adjusting manner; an observation hole is formed in the support table and below the detecting eyepiece; the detecting eyepiece is a focusable eyepiece; a capture device is arranged at the tail end of the detecting eyepiece, and connected to a processor for processing an image through a data wire. By adopting the stress detector, the brightness of a measurement area is obtained by related information of the image captured by a camera; the rotation angle is also automatically read by a code inside the manually rotating analyzer. Therefore, an error in an artificial measurement can be removed; furthermore, stress existence and distribution condition can be easily observed by adopting a photosensitive color process in the detector; the detection accuracy is high.
Description
Technical field
The present invention relates to a kind of stress detection device, particularly a kind of automatic glass tension gauge.
Background technology
Carry out the stress ga(u)ge of glass detection for traditional employing penalty method, measurement result can be subject to the impact of operator self judgement, operating personnel's difference, measurement data also can be variant, because the brightness of measured zone and reading in penalty method of analyzer angle are all with the naked eye observed, the error ratio that the data that it reads exist is larger, and therefore artificial measurement numerical result is accurate not, can not meet the needs of experiment test.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of automatic glass tension gauge of high-acruracy survey.
The present invention for the technical scheme that solves its technical matters and adopt is: a kind of automatic glass tension gauge, comprise polariscope, analyzer and detection eyepiece, described polariscope is arranged on the upper surface of base, also be provided with a brace table directly over base, but described analyzer manual rotation is arranged on brace table, detect the adjustable brace table top that is installed on of eyepiece, and the brace table be positioned under the detection eyepiece is provided with a viewport, described detection eyepiece is the adjustable focus eyepiece, the end of described detection eyepiece is installed an image-taking device, described image-taking device connects a processor for the treatment of image by data line.
As a further improvement on the present invention, described image-taking device is a USB camera.
As a further improvement on the present invention, also being provided with a proof stress instrument on described brace table adopts penalty method or sensitive color method to detect the selection lever of analyzing.
The invention has the beneficial effects as follows: employing should the power detector after, the brightness of measured zone is to provide relevant information by camera gained image, and the anglec of rotation is also read automatically by the coding of the analyzer inside of manual rotation, therefore, the error in the time of can eliminating artificial measurement; And, adopt the sensitization color method in this instrument can easily observe stress existence and distribution situation, and the precision detected is high.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, indicate: the 1-polariscope; The 2-analyzer; 3-detects eyepiece; The 4-base; The 5-brace table; The 6-image-taking device; The 7-processor; 8-selects lever.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
Fig. 1 shows a kind of embodiment of a kind of automatic glass tension gauge of the present invention, comprise polariscope 1, analyzer 2 and detection eyepiece 3, described polariscope 1 is arranged on the upper surface of base 4, also be provided with a brace table 5 directly over base 4, but described analyzer 2 manual rotations are arranged on brace table 5, detect adjustable brace table 5 tops that are installed on of eyepiece 3, described detection eyepiece 3 is the adjustable focus eyepiece, the end of described detection eyepiece 3 is installed an image-taking device 6, described image-taking device 6 connects a processor for the treatment of image 7 by data line, described image-taking device 6 is a USB camera, also being provided with a proof stress instrument on described brace table 5 adopts penalty method or sensitive color method to detect the selection lever 8 of analyzing.
Sample is placed on polariscope, and bottom can be sent linearly polarized photon and be impinged upon on sample, and when sample contains stress, due to phase differential, linearly polarized photon can be converted into elliptically polarized light.Two kinds of different phase differential wave plates are arranged on polariscope, can be switched by lever.Wherein a kind of for penalty method, another kind of for sensitive color method.The optic axis direction of these two kinds different phase differential wave plates is preformed.
When selecting penalty method, can will change once again linearly polarized photon into because sample interior stress changes from linearly polarized photon the elliptically polarized light come, because polarization angle now depends on the ellipticity of elliptic polarization, if can make brightness of image reach minimum value to a certain angle by the pivot analysis device, light delay and stress value can automatically be calculated and are presented on computer monitor by the appended software of computer.
When selecting sensitive color method, the phase differential of sample can show with naked eyes visible wavelengths band.The whole visual field can be revealed as aubergine, and this color is called " sensitization look ".If sample has stress, color sample can be shown in green, blueness, and crocus, yellow or other colors, therefore can see the distribution of stress, and distinguish tension stress direction and compressive stress direction.
Appended software can store images and much information, such as picture and result of calculation etc.Equally also can read and show this type of data.Same, this software can be changed the measurement result layout, reads the operations such as metrical information and printing.Can also be edited and be preserved with the csv form data independently, can in EXCEL, be carried out data edition.
