摘要
在光电检测领域,激光三角法是一项优越且广泛应用的技术,它具有高精度、快速、非接触的优点。文中将该技术应用于微位移的测量,提出了一种激光式微位移传感器,建立该传感器的数学模型,然后考虑高精度、小尺寸的要求,分析了该传感器的光路系统参数。文章的研究分析为该传感器的具体实现提供了有效的参考依据。
In the field of photoelectric detection, laser triangulation is a superior and widely used technology with advantages of high accuracy, high speed, and non-contact. This paper applied it to the measurement of micro-displace- ment. It proposed and designed a laser-type micro-displacement sensor. The paper first created the mathematical model of the sensor, afterward analyzed the optical parameters of the sensor in light of the requirements of high accuracy and small size. This research provides an effective reference basis for the realization of the sensor.
