    • A method includes illuminating (902) a material (102, 202, 302) with first light (108, 208, 308, 504, 604, 802) along an optical path. The method also includes capturing (904) an image (400, 450, 480, 700, 750) of second light (114-116, 214-216, 314-316, 804, 808, 814, 816, 822) transmitted through the material using a first detector (118, 218, 318, 806, 812, 820, 826, 830), where a first portion of the second light follows the optical path of the first light and a second portion of the second light diverges from the optical path. The method further includes capturing (906) one or more measurements of third light (126, 226, 326) using a second detector (124, 224, 324, 821). The third light diverges from the optical path by a larger amount than the second portion of the second light, and the second detector is spaced apart from the first detector. In addition, the method includes determining (912) one or more haze values associated with the material based on the image and the one or more measurements and at least one of storing and outputting (912) the one or more haze values.
    • 一种方法包括沿光路照射(902)的材料(102,202,302)与第一光(108,208,308,504,604,802)。因此,该方法包括:捕获(904)的图像(400, 450,480,700,750)的第二光(114-116,214-216,314-316,804,808,814,816的,822)反式穿过材料mitted使用第一检测器(118,218,318,806 ,812,820,826,830),其中所述第二光的第一部分沿着所述第一光的光路和第二光的第二部分从光路发散。该方法还包括捕获(906)的一个或 更多测量使用第二检测器(124,224,324,821)的第三光(126,226,326)的。 第三光从由比所述第二光的第二部分大的量的光路发散,并且所述第二检测器从所述第一检测器间隔开。 此外,该方法包括基于在图像上的材料和所述一个或多个测量和存储和输出婷中的至少一个(912)所述一个或多个的雾度值相关联的确定性开采(912)一个或一个以上的雾度值。
