雷射追蹤儀輔助量測架的設計

Abstract

本篇論文是針對雷射追蹤儀接受光源的反射稜鏡的支撐架的改善做討論，首先介紹何謂雷射追蹤儀，雷射追蹤儀乃是一能將雷射光射出至反射稜鏡並接受反射稜鏡所反射回來的雷射光，而這反射回來的雷射光含有兩種資訊，就是反射稜鏡至雷射追蹤儀的距離和方向，因此藉由雷射追蹤儀我們能測知反射稜鏡中心的座標， 但是反射稜鏡中心與徒測面的接觸點有一段距離，而本篇論文即是討論如何直接量測待測點的點座墂，美國所使用的解決方法乃是利用光學的方法，本文所使用的方法乃是幾何方法，而使用幾何方式須要製做輔助探棒，但是由於量測時我們必須用手拿著輔助探棒，由於手會抖動因此是屬於動態量測，於是我們即製做輔助架使得探棒量測成為靜態量測，以減少誤差，另一方面我們也在計算方法上進行改善，使得量測誤差的影響減少。

We disscussed the improvement of the frame of Laser tracker's corner cube in this paper. First, we introduce what Laser tracker is. Laser tracker can shoot laser light to the corner cube and can accept the reflected laser light from the corner cube. The reflected laser light over Look two kind of information which are the distance from the corner cube to laser tracker and the way frome the corner cube to laser tracker, so we can know the coordinate of the center of the corner cube by the Laser tracker. But there is some distance from the center of the corner cube to the point on the surface which we want to measure. We discuss how to measure the point which we want to measure on the surface directly in this paper. Americans use the optics way to solve the problem but we use geometrical way to solve it. We need to use the assistant measuring frame if we use the geometrical way. We must use our hands to take the assistant measuring frame when we are measuring. Our hands can shake, so it is not the static measuring. We make the thelf to let the measuring be static to reduce error. We improve the way of caculating to reduce error.
