Definitions
- the illumination unit may further include an aperture disposed between the light source and the detecting prism along the optical path for blocking at least a portion of the incident light incident on the detecting surface to be less than a critical angle of the total reflection Light. More preferably, the aperture is positionally adjustable in a direction perpendicular to the optical path.
- the detection prism may also include a reflective surface that reflects light entering the detection prism and directs it to the detection surface.
- FIG. 1 is a schematic structural view of a glass surface stress detecting device according to Embodiment 1 of the present invention.
- the glass surface stress detecting device 100 includes an illumination unit 10, a detecting prism 20, and an imaging unit 30.
- the light source in the illumination unit 10 includes a laser 12 and a collimating beam expander 13.
- the laser emitted by the laser 12 has good monochromaticity, good coherence, good directivity and high brightness.
- the collimator beam expander 13 is used to enlarge the diameter of the beam from the laser 12 such that the beam entering the cylindrical mirror 15 is a collimated beam.
- the lighting unit 10 may further include a polarizer 16 for selecting light of a certain polarization direction
- the detecting prism 20 is irradiated.
- the certain polarization direction is, for example, a direction approximately 45 degrees from the normal plane of the optical path, but is not limited thereto.
- the polarizer 16 can be disposed at any suitable location in the optical path prior to detecting the prism, such as between the cylindrical mirror 15 and the detection prism 20 as shown in FIG. Where the light source comprises a laser, the polarizer 16 may or may not be used.
- the imaging unit 30 may further include a mirror 31 disposed between the detecting prism 20 and the quartz wedge 32 and an adjusting device (not shown) for adjusting the position and posture of the mirror 31.
- a mirror 31 is placed between the detecting prism 20 and the quartz wedge 32 and adjacent to the detecting prism 20 to reflect the light emitted from the detecting prism 20 into the quartz wedge 32.
- the position of the mirror 31 adjacent to the detecting prism 20 can be adjusted by the user via the adjusting means to adjust the angle of the light entering the lens group 34.
- the adjustment device can be a wire assembly to improve ease of use and adjustment accuracy.
- the glass surface stress detecting device 100 may further include an image detecting unit 35 that detects an image formed by the imaging unit 30.
- Image detecting unit 35 It may be a charge coupled device (CCD) camera, and a light of a critical angle incident from the detecting prism 20 passes through the lens group 34 and is imaged onto the CCD camera 35.
- CCD camera As a new type of photodetector, CCD camera has the ability to store and transfer information charges, and can directly complete the acquisition, conversion, storage and output of spatial information.
- the glass surface stress detecting device 100 may further include a cover 40.
- the cover is preferably a light-shielding cover.
- the light shielding cover 40 houses the above-described illumination unit 10, detection prism 20, imaging unit 30, and the like for shielding stray light from the outside.
- a part of the light emitted from the illumination unit 10 having an incident angle smaller than the critical angle of the total reflection angle enters the glass to be detected and is reflected back, and enters the detecting prism 20 again to become an interference light.
- the function of the aperture 17 is to block this portion of the incident light that may interfere with the light before it is incident on the detecting prism 20.
- the aperture 17 is along a side perpendicular to the optical path The orientation is adjustable for different applications, especially where the critical angle of total reflection is different due to the different refractive indices of the glass being tested. As shown in FIG. 2, the aperture 17 can be placed between the light source 11 and the cylindrical mirror 15.

Abstract
La présente invention concerne un dispositif de détection de contrainte de surface de verre qui comprend une unité d'éclairage (10), un prisme de détection (20) et une unité d'imagerie (30). L'unité d'éclairage (10) est utilisée pour fournir une lumière d'éclairage polarisée et comprend une source de lumière. Le prisme de détection (20) comprend une surface de détection (20a) utilisée pour ajuster la surface du verre détecté pour la détection. L'unité d'imagerie (30) comprend un coin de quartz (32), une plaque d'analyseur (33) et un groupe de lentilles (34) qui sont disposés de manière séquentielle le long d'un trajet de lumière. L'unité d'éclairage (10) comprend également un miroir cylindrique (15). Le miroir cylindrique (15) est disposé entre la source de lumière et le prisme de détection (20) et présente une puissance de réfraction radiale positive et le miroir cylindrique (15) est conçu pour permettre que la direction axiale du miroir cylindrique disposé (15) soit perpendiculaire à un plan normal de trajet de lumière commun où des normales d'au moins une partie de la lumière et d'une surface de détection (20a) sont situées. Le miroir cylindrique (15) fait converger la lumière d'éclairage, la lumière incidente sur la surface de détection (20a) du prisme de détection (20) comprend différents angles d'incidence d'angles critiques de réflexion totale et, par conséquent, un travail manuel sur un réglage d'angle d'incidence peut être atténué ou omis et le dispositif de détection de contrainte de surface de verre comporte une structure intégrale plus compacte.
