方法,装置和物品,以便于使用电磁能量对物体的分布评估

Method, apparatus, and article to facilitate distributed evaluation of objects using electromagnetic energy
Abstract:
Objects such as manufactured goods or articles, works of art, media such as identity documents, legal documents, financial instruments, transaction cards, other documents, and/or biological tissue are sampled via sequential illumination in various bands of the electromagnetic spectrum, a test response to the illumination is analyzed with respect to reference responses of reference objects. The sequence may be varied. The sequence may define an activation order, a drive level and/or temperature for operating one or more sources. Illumination may be in visible, infrared, ultraviolet, or other portions of the electromagnetic spectrum. Elements of the evaluation system may be remote from one another, for example coupled by a network.
