Abstract

We propose a new commercial laser triangulation sensor modification to enable the measurement of slots or bores side distance. The study showed the possibility of extending the sensor depth range for a slot or bore side distance measurement using a bypass of the illumination laser beam compared to a simple single mirror attachment to the sensor probe. We derived relations allowing for evaluation of the modified sensor side measurement range in desired depth based on the sensor parameters and the reflective mirror size and position. We demonstrated the functionality of the proposed measurement arrangement with an attachment to the commercial laser triangulation sensor and assessed the side-wall distance measurement. The results show the correct measurement depth and range prediction and the ability to perform side surface distance measurements at depths of more than 3.5 times the slot size.

摘要

我们提出了一种新型商用激光三角测量传感器的改进方法，以实现对槽或孔侧面距离的测量。研究表明，与简单地在传感器探头处安装单个反射镜相比，通过照明激光束的旁路来扩展传感器深度范围以进行槽或孔侧面距离测量是可行的。我们推导了一些关系式，可根据传感器参数以及反射镜的尺寸和位置来评估改进后传感器在所需深度处的侧面测量范围。我们通过在商用激光三角测量传感器上附加装置展示了所提出测量装置的功能，并评估了侧壁距离测量。结果表明能够正确预测测量深度和范围，并且能够在深度超过槽尺寸3.5倍的情况下进行侧面距离测量。
