| 中文摘要: |
| 本文提出了一种提高测量灵敏度的光弹性贴片法。通过高频条纹调制获取载波条纹图。使贴片的等差效应所反映的力学信息规范化。运用计算机图象处理技术,对载波图自动采集、处理和解调,以获得全场条纹级数。编制了专用软件并以实例说明实验过程。 |
| 英文摘要: |
| The present paper proposes a new method for inpaouing sensitivity of photoelastic coating. The fringe pattern of coating is modulated by a high frequency family which is called photocarrier. The isochromatic information is converted into deviation of stan |
