A method includes illuminating (902) a material (102, 202, 302) with first light (108, 208, 308, 504, 604, 802) and capturing (904) an image (400, 700) of second light (114-116, 214-216, 314-316, 804, 808, 814, 816, 822) transmitted through the material. The method also includes analyzing (908) multiple regions (402-406, 702) of the image and determining (910) one or more haze measurements associated with the material based on the analyzing. The method further includes storing and/or outputting (910) the one or more haze measurements. Analyzing the multiple regions of the image may include summing pixel values in each region to produce a total pixel value for that region. The multiple regions of the image may include (i) a first region forming a first disc, (ii) a second region forming either a first annular region around the first region or a second disc larger than and including the first disc, and (iii) a third region forming either a second annular region around the second region or a third disc larger than and including the first and second discs. |
