Abstract:	本研究首先是利用零次平衡補償器與標準懸臂梁校正試驗，在相同光圈值不同快門條件下進行彩色光彈應力條紋與相對應之RGB值探討，並決定標準光彈應力條紋級次之RGB值，作為反射式光彈法的數位差異化影像處理之標準，本研究整合反射式光彈法與鑽孔法，在混凝土矩形試體上施加一固定之預壓應力，並於混凝土試體表面黏貼光彈貼片，配合鑽孔法在光彈貼片附近鑽孔，利用反射式光彈儀進行預壓混凝土之預應力研究，經由光彈貼片上之應力條紋變化，配合數位影像差異化處理技術，可計算得到鑽孔周圍光彈貼片上之釋放應力與殘餘應力之應力場，進而與彈性力 This paper aims at using null-balance compens-ation instrument and standard cantilever beam test to probe into RGB of color image stress fringe order and decide RGB of standard fringe order which is going to be the standard processing of digital image dis
