Method and apparatus for creating images of fibrous structures

摘要

Apparatus and method for rendering an image of a fibrous material. The method includes providing parametric fibrous material optical properties derived from actual material fiber samples via the apparatus; providing a parametric virtual light environment; providing a virtual fibrous material array; and rendering an image of the virtual fibrous material array according to the interaction of the parametric fibrous material properties and the parametric virtual light environment.

1. An apparatus for determining material optical properties, the apparatus comprising:
a. a material holder comprising a curvilinear surface; b. a collimated light source disposed in alignment with a surface normal of the curvilinear surface, to illuminate the material holder, wherein the collimated light source has an output; and c. an image capture element aligned with the collimated light source and the surface normal of the curvilinear surface of the material holder;wherein an angular offset between an axis of the collimated light source and an axis of the image capture element, each in a plane of the surface normal of the curvilinear surface of the material holder, is less than about 5 degrees; andwherein a surface mirror and a half silvered mirror are disposed to bring the output of the collimated light source into alignment with the axis of the image capture element and to illuminate an image capture surface.
