四相圖英語怎麼說及英文翻譯

A. 英文翻譯

In this work, the projected fringes were shifted using a mirror mounted on a rotary stage placed in the path of the illumination as shown schematically in Fig. 2(b). 在本文中，被投影的條紋用一個安裝在旋轉台上的反射鏡偏移，而旋轉台則放置在照明的路徑上，就像圖2（b）中示意的那樣。The projector is a standard slide projector (Braun Novamat 130AF). 投影儀是一種標準的幻燈片投影儀（Braun Novamat 130 AF）。A sinusoidal grating was generated using a computer program written using Matlab and prepared onto a 35 mm slide. 用一個用Matlab編寫的計算機程序產生一個正弦光柵，並被制備在一片35mm的幻燈片上。A 640×480 resolution monochrome CCD camera (JAI CV-M50) placed at approximately 600 mm from the object was used to capture the image. 採用一台放置在離物體約600mm處的640×480 解析度的黑白CCD攝像機（JAI CV-M50）來捕集圖像。Figures 3(a)–(c) show images of fringes projected on to the glass blocks and shifted by 2π/3 radians in three stages. 圖3（a）－（c）示出了投射到玻璃塊上，並在三個階段中被偏移2 π/3弧度的條文的圖像。The phase map obtained after applying Eq. (3) to these images is shown in Fig. 3(d). 在將式（3）用於這些圖像後得到的相點陣圖始於圖3（d）。Phase value 0 corresponds to gray value 0 in the phase map image, whereas phase value 2π corresponds to gray value 255. 相位值0對應於相點陣圖圖像中的灰度值0，而相位值2π對應於灰度值255. Other phase values are linearly related to the pixel intensity from 0 to 255. 其他相位值與從0到255的像素強度成線性關系。
The projection angles of the non-collimated light for a given height on the surface of the specimen block have to be determined before calculation of tilt can be performed. 對於在樣本塊表面上的某一給定高度來說，非準直光的投影角必須先確定，才能進行傾角的計算。To determine the relationship between θ and block distance L along a straight line from the origin O, a single glass block of dimensions 13.5 mm×152.0 mm×15.0 mm was used. 為了確定θ與從原點O起沿直線的玻璃塊距離L之間的關系，採用了尺寸為13.5mm×152.0mm×15.0mm的單一玻璃塊。The block was made from eight pieces of glass with an average thickness of 2 mm each, bonded together using adhesive compound. 該玻璃塊由8片玻璃製成，每片的平均厚度為2mm，用黏結化合物黏結在一起。
Figure 4(a) shows the block with the projected fringe pattern and Fig. 4(b) is the phase map for the block. 圖4（a）示出了帶有投影條紋圖形的玻璃塊，圖4（b）為該玻璃塊的相點陣圖。The position of the blocks is not identical in these two figures because the image in Fig. 4(a) was shifted to the left to show the shadow at the edge of the block. 玻璃塊的位置在這兩張圖中不是同一的，因為圖4（a）中的圖像被偏移到左面，以顯示玻璃塊邊緣處的陰影。The shadow was used to determine the location of the fringe break point from the background to the block surface. 該陰影被用來確定從背景到玻璃塊表面，條紋中斷點的位置。This information was used to determine the phase break points in the phase map. The dots in Fig. 4(b) show the phase breakpoints from block to background, where A1 corresponds to A2 and A′1 corresponds to A′2. The break points have the same gray values. 這一信息被用於確定相點陣圖中的相位中斷點。圖4（b）中的圓點表示從玻璃塊到背景的相位中斷點，其中，A1對應於A2，而A』1對應於A』2。中斷點都有相同的灰度值。
Once the corresponding break points on the block and the background were located the gray values along a horizontal line from both points were read using a C++ program linked to the Matrox Imaging libraries. The gray values were read from left to right using the edge of the block as the limit. Completion of this step resulted in two sets of data with gray values and coordinates along the block. The intensity distribution is represented by gray values ranging from 0 to 255.
一旦玻璃塊上對應的中斷點和背景被定位，那麼沿來自兩點的水平線的灰度值就可用鏈接到Matrox成像庫的C＋＋程序讀出。灰度值用玻璃塊的邊緣作為極限而從左到右讀出。這一步驟的完成能得到兩組數據，即灰度值和沿玻璃塊的坐標。光強分布用0到255范圍的灰度值來表示。
