摘要
介绍了新型激光位敏探测器(PositionSensitiveDetector,PSD)的结构、特点及其工作原理;结合一维激光PSD在三角测量中的应用,给出了测量系统的主要组成;讨论了激光PSD在实际应用中的一些关键技术问题.最后给出了一个在线连续检测应用实例.应用结果表明,即使被测目标在运动状态下,这种检测系统仍然能获得非常满意的测量效果.
The structure, the character and the operating principle of a new laser-based position sensitive detector (PSD) are introduced. The application of one-dimensional laser-based PSD in optical triangulation being taken as an example, the basic constitution of the triangulation system is presented. Some key techniques in the application of the laser-based PSD are discussed. A case of on-line measurement shows that, even if the object to be measured is moving, the measurement system can still gain satisfied result.
