工业上很需要对一些板材、带材厚度进行在线测量,但一直缺少一种合适的非接触式动态测厚仪器。上海交通大学最近研制成功的激光动态测厚样机,就是利用激光对运动状态下的板、带材厚度作非接触式无损检测的新颖装置。 该仪器包括主机、信号处理系统、微型计算机及电源四部分,能实现非线性、双测、动态实时检测。由于在仪器中采用了双测不对称接收系统,扩大了激 There is a great need in the industry for on-line measurements of some sheet and strip thickness, but a suitable non-contact, dynamic thickness gauge has been lacking. Shanghai Jiaotong University recently successfully developed laser dynamic thickness measurement prototype, is the use of laser motion of the plate, strip thickness non-contact non-destructive testing of novel devices. The instrument includes the host, signal processing system, microcomputer and power supply four parts, to achieve non-linear, dual test, dynamic real-time detection. As the instrument used in a double test asymmetric receiving system, expanded shock
