摘　　要：提出了一种基于环形激光的深孔内膛检测系统,该系统主要由环形激光发生器、反射锥镜、CCD相机以及驱动装置等组成。通过对环形激光器投射在被测身管内膛上的环形光斑进行成像和分析计算,可对身管内膛的一个截面形廓进行检测,并在驱动装置的驱动下,实现对深孔内膛形貌的三维检测。A detection system based on ring laser is proposed for the inner wall of deep hole. The system mainly consists of ring laser, reflecting prism, CCD camera and driving unit. The inner wall cross-section pattern of a deep hole can be detected through imaging, analyzing and calculating the ring spot projected on inner wall of deep hole by ring laser. 3-D detection for inner wall pattern of deep hole can be carried out under the driving of the driving unit.
