Abstract
一种光路调制器(300)，应用于指纹识别装置(130)，用于将从手指表面反射回来的反射光导引至设置在光路调制器(300)下方的光学检测单元(134)，光学检测单元(134)用于对接收到的反射光进行检测，其中，光路调制器(300)的上表面与下表面之间具有通孔阵列，通孔阵列包括多个倾斜通孔，其中每个倾斜通孔的倾斜角度大于0°，倾斜角度为倾斜通孔的轴线方向与垂直于光路调制器(300)表面的法线方向之间的夹角。由于该光路调制器(300)具有由倾斜通孔组成的通孔阵列，在相同孔深的情况下，可以得到更薄的光路调制器的(300)厚度。并且，通过调整光路调制器(300)里边的倾斜通孔的倾斜角度，可以有效地改变光路的传播路径和角度，使其对光路的调制更为灵活。
