Abstract
An illumination chamber for illuminating an object with substantially uniform illumination and providing an image of the object, the illumination chamber includes a generally 6-faced polyhedron opaque housing, which encloses a light mixing chamber. The housing includes an object transparent glass sheet, an image transparent glass sheet and at least one light source disposed inside the housing. The object transparent glass sheet is disposed at a first of the two larger faces of the 6-faced polyhedron and image transparent glass sheet is disposed at the second large face of the 6-faced polyhedron, opposing the object glass sheet. The object to be imaged, typically a document, is disposed immediately adjacent to the external surface of the object transparent glass sheet. The image of the objects exits the housing through the image transparent glass sheet.
