本研究開發之雷射探頭其量測範圍為±2 mm，解析度為0.9 μm，工作距離約為10mm，軟體搭配LabVIEW程式做量測程式撰寫，結合三軸運動平台與雷射探頭，建構自動化量測系統。在提出的量測模組中，針對不同材質進行量測模組比較，根據實驗結果應用在量測實例工件上，量測模組以五個CCD取平均值法、五個CCD取中值法、六個CCD取平均值法為較佳量測方式。在量測誤差比對方面，以三次元座標量測儀(C.M.M.)之量測結果作為比對基準，量測工件有代木材質之階高工件、圓柱面工件、斜面工件、白色紙板水平面與木材之半木圓球，並探討以表現較佳模組量測方式之量測結果。

This study aims to develop an improved triangulation laser probe based on the previous study of the precision-scattering multi-sensor triangulation laser probe. The optical path design was based on the Scheimpflug principle, so that the laser spot projected onto the surface of the sensor was constantly focused and imaged. The hardware structure of the developed probe consisted of a micro-focus laser, six Linear CCD sensors with ring-shaped arrangement. The circuit design of the measurement system was changed from the solderless breadboard to the Printed Circuit Board, which reduced the volume of the whole system, and stabilized the signals. In terms of driving Linear CCD, we used the microcontroller Arduino Mega2560 to generate the required signals, which reduced the driving cost and increased the convenience of changing the driving parameters. In terms of the CCDs, the previous type, TCD1503-DG, was replaced with a new one, TCD1705-D, which improved the measurement accuracy and the point data extraction significantly.
The measurement range of the laser probe developed in this study was ±2 mm, and the resolution was 0.9 μm. A collocation of measurement software was developed by the LabVIEW. A three-axis motion platform and the laser probe were integrated to construct an automated measurement system.
Different measurement modules were compared for the specimens with different materials. The proposed measurement modules were the averaging methods calculated by five CCDs, the median method determined by five CCDs and the averaging methods by six CCDs.
The measurement errors of the development laser probe were verified by a Coordinate Measuring Machine (C.M.M). The measurement test workpieces included the stepped workpiece, the cylindrical surface workpiece, the bevel plane workpiece, the white cardboard plane, and the wood half-sphere workpiece. According to the performance test results, the three proposed measurement modules were used for the measurement results.
