2.3 Development of reference table Since the θ-L relationship is different for different block heights, the projection angle calibration must ideally be performed for the specific height each time the height measurement needs to be carried out. Since this is not practical, a reference table was developed that can be used
to find the θ-L relationship for any object heights by interpolation.
The projection angle calibration was carried out for different block heights to obtain the reference table. Six pieces of glass plates of approximate thickness 2 mm each were used. The calibration was first done at 2 mm height using a single piece, than the height was increased until all six pieces were placed together, giving an overall height of approximately 12 mm. Adhesive compound was not used to attach the glass pieces to avoid errors due to non-uniform compound thickness. The projection angle variation was determined as before by scanning the block surface and the background in the phase map and subtracting the pixel coordinates of points having the same intensities. The actual heights of the glass block pieces were measured using the laser sensor. This method was used to generate the reference table for θ-L relationship for any height less than 12 mm. The data were linear-fitted using the leastsquares method and are shown in Fig. 7. The linear-fitted data were used to obtain the reference table (Table 1). The θ-L relationship for any height within 12 mm can be
obtained by interpolation from the reference table.
2.4 Projection angle variation across the field of view In addition to varying with height, the projection angles for a non-collimated light source also varies across the field-ofview (FOV). To investigate the error introduced by the projection angle variation across the FOV, the heights of four glass blocks, positioned across the FOV, were calculated using the θ-L relationship formulated from the reference table for a fixed location. The average heights of
each glass block were measured using the laser instrument at selected points at 10 mm interval. The average heights of the four blocks measured using the laser instrument were, respectively, 5.72 mm, 5.70 mm, 5.81 mm and 5.73 mm and the mean height of all four blocks is 5.74 mm. Since the projection angle calibration was previously done for the height of 5.73 mm (Table 1), it was not necessary to carry out interpolation from the reference table due to the small difference in height (0.01 mm). The equation derived for the illumination angle at height 5.73 mm is given by:

2.3 Development of reference table
2.3 参考表的制定
Since the θ-L relationship is different for different block heights, the projection angle calibration must ideally be performed for the specific height each time the height measurement needs to be carried out. 由于对不同的玻璃块高度，θ-L 关系是不同的，所以投影角的定标理想来说必须在每当需要进行高度测量时的特定高度下进行。Since this is not practical, a reference table was developed that can be used to find the θ-L relationship for any object heights by interpolation. 因为这不现实，所以制定了一份能用插值法找出任何物体高度下θ-L关系的参考表。The projection angle calibration was carried out for different block heights to obtain the reference table. 在不同玻璃块高度下进行了投影角的定标，以获得此参考表。Six pieces of glass plates of approximate thickness 2 mm each were used. 采用了每片约2mm厚的6片玻璃片。The calibration was first done at 2 mm height using a single piece, than the height was increased until all six pieces were placed together, giving an overall height of approximately 12 mm. 定标先在2mm的高度用一片单片进行，然后将高度增加，直至全部6片都放在一起，整个高度达到约12mm为止。Adhesive compound was not used to attach the glass pieces to avoid errors due to non-uniform compound thickness. 玻璃片附在一起不用黏结化合物，以避免因化合物厚度的不均匀引起的误差。The projection angle variation was determined as before by scanning the block surface and the background in the phase map and subtracting the pixel coordinates of points having the same intensities. 投影角的变化像以前一样，通过扫描玻璃块表面和相位图的背景，并减去具有相同光强的点的像素坐标而确定。The actual heights of the glass block pieces were measured using the laser sensor. 玻璃块玻璃片的实际高度用激光传感器测量。This method was used to generate the reference table for θ-L relationship for any height less than 12 mm. 这种方法被用来产生低于12mm的任何高度下θ-L 关系的参考表。The data were linear-fitted using the least squares method and are shown in Fig. 7. 数据用最小二乘法线性拟合，并示于图7。The linear-fitted data were used to obtain the reference table (Table 1). 线性拟合的数据即用于得到参考表（表1）。The θ-L relationship for any height within 12 mm can be obtained by interpolation from the reference table. 在12mm以内任何高度下的θ-L关系可以通过插值从参考表获得。
2.4 Projection angle variation across the field of view
2.4 跨视场的投影角变化
In addition to varying with height, the projection angles for a non-collimated light source also varies across the field-ofview (FOV). 除了随高度变化外，非准直光源的投影角也跨视场（FOV）而变化。To investigate the error introduced by the projection angle variation across the FOV, the heights of four glass blocks, positioned across the FOV, were calculated using the θ-L relationship formulated from the reference table for a fixed location. 为了研究因投影角跨FOV的变化所感生的误差，4个跨FOV定位的玻璃块的高度用固定位置下的参考表公式化的θ-L关系进行了计算。 The average heights of each glass block were measured using the laser instrument at selected points at 10 mm interval. 每个玻璃块的平均高度用激光仪器在以10mm间隔选择的点处进行测量。The average heights of the four blocks measured using the laser instrument were, respectively, 5.72 mm, 5.70 mm, 5.81 mm and 5.73 mm and the mean height of all four blocks is 5.74 mm. 用激光仪器测得的4块玻璃块的平均高度分别为5.72 mm, 5.70 mm, 5.81 mm and 5.73 mm，而全部4块玻璃块的平均高度为5.73mm。Since the projection angle calibration was previously done for the height of 5.73 mm (Table 1), it was not necessary to carry out interpolation from the reference table due to the small difference in height (0.01 mm). 因为投影角的定标以前是在5.73mm高度下进行的（表1），高度的差别很小（0.01mm），所以不必要从参考表插值。The equation derived for the illumination angle at height 5.73 mm is given by: 在5.73mm高度下为照明角推导的方程式给出如下：
