本文介绍了一种新设计的传感器，它具有同时检测光斑的二维位置和一维角度的能力。普通的基于激光的测量系统利用CCD或PSD传感器。这些传统的传感器只能检测一个光点的位置。当传感器既能检测出光斑的入射角又能检测出光斑的位置时，传感器的适用范围就很广。该传感器由两个线性阵列型传感器组成，其深度位置略有不同。我们已经设计并建立了一个原型传感器系统。我们通过实验验证了本传感器系统的实用精度。我们还将本传感器系统应用于两个典型的基于激光的测量系统：2-D位置测量和镜面物体的3-D形状测量。实验结果表明，该传感器系统适用于基于激光的测量系统。
The present paper describes a newly devised sensor, which has the ability to detect the two-dimensional position and the one-dimensional angle of a light spot simultaneously. Ordinary laser-based measurement systems utilize CCD or PSD sensors. These conventional sensors can detect only a light spot's position. When the sensor can detect the incident angle of a light spot as well as the position, the sensor has a wide range of applicability. The sensor consists of two linear array-type sensors whose depth positions are slightly different. We have designed and built a prototype sensor system. We experimentally verified the practicable accuracy of the present sensor system. We also applied the present sensor system to two typical laser-based measurement systems: 2-D position measurement, and 3-D shape measurement for specular objects. Experimental results show that the sensor system was applicable to a laser-based measurement system.
