    摘要: 本研究以量測拍翼式微飛行器翼膜表面之壓力變化為主要目標，所採用技術係透過壓力感測塗料之氧淬滅效應，以影像分析辨別表面螢光亮度變化進行表面壓力量測，期望獲得連續、準確的翼膜表面壓力分佈。
    實驗基材為聚對二甲酸乙二醇酯(PET)，選用Rudpp作為螢光高分子材料，並以RTV118為黏著劑，再加入TiO2做為光散射劑，經由氮氣噴流實驗，於噴流傾斜角5度，噴流高度/管徑為0.5，出口壓力4.5 Pa之壓力下進行螢光量測，其平均螢光亮度變化可達6%。
    以壓力腔體量測壓力與螢光校正曲線，並結合14-bit高解析度相機擷取影像，分析於0.5大氣壓的壓力變化下，其螢光亮度變化為26%，最小壓力解析度為11.5 Pa，適合運用於微小壓力量測。
    The purpose of the study is to measure the pressure distribution on flapping-wing surface. The authors applied the oxygen quenching by pressure sensitive paint measurement system and used image processing and analysis technology to measure fluorescence intensity change. Through expect continuous and accurate surface pressure distribution of wing membrane.
    In my experiment, I adopted PET film as the base of work piece, and spun fluorescent polymers on the film. The fluorescent polymer is mixed with RTV118 and TiO2. In this polymer, RTV118 is as adhesive agent and TiO2 is as light scattering agent. I blew the spun work piece by jetting nitrogen with an inclined angle of 5 degree, or jet height / diameter (H / D) is 0.5. A pressure of 4.5 Pa nitrogen jet was applied, and then got an average fluorescence brightness of up to 6%.
    Furthermore, for reaching feasible application of MAV, I made a pressure chamber to measure brightness under variable applied pressure. Images were recorded by a 14-bit camera and analyzed by software ImageJ. The input pressure of atmosphere was set from 1 to 1.5 atm, and then got the polymer average fluorescence intensity changes are up to 26%. From the analyzed data, the minimum pressure resolution is up to 11.5 Pa per gray value. And the fluorescence intensity is decreased with the increasing pressure as a parabola curve. Finally, the result show the fluorescent polymer is feasible to measure the pressure distribution on the flapping wing of MAV.
