Embodiment Construction

[0014] discussed below Figures 1 to 9 The various embodiments and examples used to describe the principles of the invention in this patent document are by way of illustration only and should not be construed in any way as limiting the scope of the invention. Those skilled in the art will understand that the principles of the invention may be implemented in any type of suitably arranged device or system.

[0015] Figures 1 to 3 The figures illustrate an example system for measuring the haze of sheet material or other materials according to the present disclosure. Such as figure 1 As shown in FIG. 1 , system 100 is used to measure the haze of material 102 . Material 102 here represents a moving web or sheet of non-opaque material such as plastic. However, material 102 could represent any other material(s) in any suitable form(s), such as glass.

[0016] In this example, system 100 includes light source 104 and optics 106 used to generate collimated beam 108 . Light sourc...

Abstract

A method includes illuminating a material with first light and capturing an image of second light transmitted through the material. The method also includes analyzing multiple regions of the image and determining one or more haze measurements associated with the material based on the analyzing. The method further includes storing and / or outputting 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.

Description

technical field [0001] The present disclosure relates generally to measurement systems, and more particularly to an apparatus and method for measuring the haze of sheet or other materials. Background technique [0002] Many transparent, translucent, or other non-opaque materials are fabricated into long webs or sheets. One property of these types of materials is haze, which generally refers to the scattering of light through such materials. Haze generally reduces the contrast of objects viewed through the material. For example, haze in plastic sheets used in product packaging may reduce the clarity of printed text viewed through the plastic sheets. Low haze may be important or necessary for certain applications such as consumer electronics packaging or medical device packaging. [0003] Haze measurements typically take place in laboratory settings. For example, a sample of material can be placed against the entrance of an integrating sphere where the haze of the sample c...
