| 中文摘要: |
| 本文提出了光载波条纹图的锁相处理方法,以对光载波条纹图作精确定位。给出了适合于计算机处理的离散递归实现步骤。在非线性模型下对定位精确度作了详细分析。实验结果表明,当暂态影响衰减后,能对条纹图进行精确定位而无稳态误差,对断裂条纹的大范围补偿也取得了较好的效果。 |

| In order to locate the fringes more exactly, the phase locked technique is employed in the method of image processing of photo carrier fringe patterns. A discrete iterated procedure, which can be processed conveniently by a computer, is discussed. The err |
