本研究以先期精密散射式多感測器三角雷射探頭研究為架構，開發一改良型多感測器三角雷射探頭。在光路設計方面，本研究以Scheimpflug原理為基礎，使投射至感測器表面之雷射光斑恆聚焦成像；硬體架構同樣以單一雷射光源搭配六個線電荷耦合元件(Linear CCD)感測器並做環型設置；本研究進行光路設計參數改良，使雷射探頭體積減少，增加機上量測之便利性；在驅動Linear CCD方面，改利用微控制器Arduino Mega2560生成所需之訊號，減少驅動成本，同時增加驅動參數改變之便利性。
本研究開發之雷射探頭其量測範圍為±2 mm，解析度為1.4 μm，軟體搭配LabVIEW程式做量測程式撰寫，同時整合三軸運動平台與雷射探頭，建構一自動化量測系統。在提出的量測模組中，針對不同顏色代木進行量測模組比較，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、木材之半木圓球，並探討以三個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 triangular laser probe. The optical path design was based on the Scheimpflug principle, so that the laser spot projected onto the surface of the sensor is constantly focused and imaged. The hardware structure of the developed probe consists of a micro-focus laser, six line CCD sensors with ring-shaped arrangement. The parameters of the optical path has been modified to reduce the volume of the laser probe and to increase the convenience of measurement integration on a CNC machine or other manipulators in the future.
In terms of driving CCD, the microcontroller Arduino Mega2560 is used to generate the required signals, which reduces the driving cost and increases the convenience of changing the driving parameters.
In this study, the measurement range of the laser probe is ±2 mm, and the resolution is 1.4 μm. A set of measurement software is developed by the LabVIEW. A three-axis motion platform and the laser probe has been integrated to construct an automated measurement system.
Different measurement modules have been compared for the specimens with different colors. The proposed measurement modules are the averaging methods calculated by five CCDs, median method determined by five CCDs and the averaging methods by six CCDs.
The measurement errors of the development laser probe have been verified by a Coordinate Measuring Machines (C.M.M). The measurement test workpieces include the stepped workpiece, the cylindrical surface workpiece, and the wood half-sphere workpiece. According to the performance test results, the three proposed measurement modules have been used for the measurement results.
