本文主要利用彩色正交條紋影像的特性，透過簡易的判別式便可將這張條紋影像分解出具三步相位移之x、y方向的二元條紋影像。此方法應用於條紋反射法便可省去大量的拍攝相位移影像時間，相機於一個位置只須拍一張影像就可同時解出x、y方向之相位值，使法向量式系統的拍攝試件過程不再繁雜。
彩色正交條紋應用於條文反射法中，首先須克服的是實際由螢幕投影出之條紋影像並不像模擬的情形容易，本文透過中值濾波、伸張強化、影像分割法與形態學的一系列影像處理分解出較平整的x、y方向條紋影像，並將解出之相位值實際套用至條紋反射法-法向量系統中，解平面鏡之形貌。
實驗量測出試件形貌，並拉出其水平曲線與垂直曲線與基準高度值為0的高度值比較。均方根誤差為0.342mm與0.445mm。而改以傅立葉轉換進行二元條紋濾波所解出之相位值帶入法向量式系統量測，其均方根誤差為0.324mm與0.41mm。最後將斜率值抹平後再進行量測，水平與垂直之均方根誤差為0.254mm與0.303mm。於最後探討其量測產生誤差的原因。

The main purpose of this study is to measure the specular profile using colorful orthogonal grid fringes. Through its characteristics, a simple discriminant can decompose this fringe image into a binary fringe image in the x and y directions with a three-step phase shift. This method is applied to the fringe reflection method can save a lot of time for shooting phase shift images. The process of shooting specimens is no longer complicated.
First we have to overcome is that the actual fringe image projected by the screen is not as simply as the simulated situation. We use a series of image processing such as median filter, stretching ,image segmentation and morphology to decompose the relatively flat x and y direction fringe images, and actually apply the resolved phase to the fringe reflection system.
The specular surface profile was measured, and the horizontal curve and vertical curve were drawn to compare with the height value of the reference height value of 0. The root-mean-square error (Vertical direction) is found to be within 0.342 mm. The horizontal direction is found to be within 0.445 mm.
Then we change the method to FFT filter to solve the phase noise.The root-mean-square error (Vertical direction) is found to be within 0.324 mm. The horizontal direction is found to be within 0.41 mm.
Last we use mean filtering to smooth the noise of the slope images. The root-mean-square error (Vertical direction) is found to be within 0.254 mm. The horizontal direction is found to be within 0.303 mm.
