We combined a modified single exposure technique and the imaging plate, which is an x-ray digital area detector, for determination of stress in a localized area. Stress value by the single exposure method is obtained from lattice strains in only two directions with a single incident x-ray beam directed at an oblique angle. However, diffraction data around a whole Debye-Scerrer ring was used in this study, and then a stress value can be accurately determined in comparison with the single exposure method. We measured the DS ring by use of the imaging plate with requiring only a short exposure time. Lattice strains in many directions on a DS ring were measured by the assistance of an image processing analyzer connected to a personal computer.

我们结合了改良的单次曝光技术和成像平板，这是一个X射线数字区域探测器，用于确定局部区域的应力。单次曝光法的应力值是在一束X射线束倾斜入射的情况下，仅由两个方向的晶格应变得到的。然而，在本研究中，使用了整个德拜-斯塞勒环周围的衍射数据，然后与单次曝光方法相比，可以准确地确定应力值。利用成像板测量DS环，只需较短的曝光时间。在连接到个人计算机的图像处理分析仪的帮助下，测量了DS环上多个方向的晶格应变。
