摘要
介绍一种利用激光束照射光杠杆镜面,用高灵敏度的线型固态图像传感器CCD自动接受激光光束偏转方位来取代传统的依靠人眼从望远镜读数获取数据,实现过程自动化,从而消除测量过程中所产生的人为因素的影响,实验测量杨氏弹性模量的相对误差为0.88%,大大提高了测量精度。这一技术将传统的物理实验改进成了一个有意义的集设计、研究、综合于一体的实验。
A photoelectric auto-measuring system of Young's elastic modulus was described that uses linear CCD sensor as the detector for auto-metrically measuring and real time display. By using this new means, the error of measuring system can be decreased much more. This technology improves the traditional physics experiment into an integral experiment with designing and research.
