Document Type and Number:
WIPO Patent Application WO2002103333
Kind Code:
B1
Abstract:
Disclosed are apparatus and associated methods for high throughput determination of haze in various materials using a contrast reduction of the materials. The system uses a plurality of the materials being measured arranged in an array on a carrier (54) with a target (66) having a background and indicia providing contrast between the indicia and background. The target (66) is viewed through the materials by a camera (76), and a computer (80) determines the haze characteristics of the samples form the observed contrast reduction.
