摘要

新光學三角量測系統發展的目的在於舊光學三角系統其量測精度的提升、體積縮小且可調整其高度使其成為價格低廉易攜帶之簡易高精度非接觸式光學量測系統。對於上下跳動2.0mm以下之物體表面資訊，其最小解析度可達次像素單位(0.1pixel)即3.79μm，相較於舊系統有著大幅度的提升(46％)。
而系統應用於物體厚度之量測上，量測結果與真實物體厚度幾乎一致，說明未來更多量測應用的可能性；另一方面，本系統提供了另一種科學量測中醫脈象的方法，可以觀測脈搏上皮膚細微的跳動情形，並準確地量測其振幅變化與頻率，頻率量測的誤差小於2.5％。

The purpose of developing the new optical triangle measurement system is promoting the measurement precision, minimizing the volume of the old one ; moreover,it can adjust its height and let it become the cheaper and more portable one, which is a simple,high precision, non-contact, optical measurement.For beating from top to bottom 2.0 mm below surface information,the minimum resolution up to the subpixel units (0.1 pixel) that is 3.79 μm, compared to the old system has a substantial increase (46 percent).
The system applied to objects thickness measurement, the measurement results of real objects and the thickness of between unanimously that the more the possibility of Measurement ; On the other hand, the system provides another kind of scientific measurement Chinese medicine Pulse way,May observe on the pulse the skin slight to beat the situation, and accurately measuring changes in its amplitude and frequency, frequency of measurement error is less than 2.5 percent.
