Described sample stage is made up compared with the unstressed material in highland of physical strength and transmittance, is dentate gyrus dish type, can realize 360 ° of rotations, finds the maximum position of stress with this.
On described sample stage, be provided with the concentric circles scale mark that the center of circle is identical, diameter is different, while carrying out image acquisition, the scale mark on platform is positioned over crystal bar to be measured on sample stage per sample, ensure crystal bar to be measured concentric with sample stage together with rotation.
Described camera is CCD(charge-coupled device) camera, have high resolving power, can self-focusing advantage.
The beneficial effects of the utility model have:
(1) in image acquisition process, the rotation of sapphire crystal bar is automatic by manually changing into, with high-resolution CCD camera replacement digital camera, whole process can one man operation complete, and has saved manpower and materials;
(2) simple to operate, whole process can operate on computers by visual software interface, in the time that crystal bar quantity to be detected is more, will greatly improve detection efficiency;
(3) in image acquisition process, the height of CCD camera can regulate, and shooting angle is accurately located, and ensures the accuracy of image acquisition, further improves the accuracy that stress detects.
