Abstract

A marking system for use with, a multi-spectral imager (10) for use in high, throughput sortation of articles having distorted or irregular surfaces is disclosed. Specific uses include, but are not limited to, document sorting, garment and textile rental operations, laundry operations, and mail and package sorting and identification. Methods and apparatus are provided to remotely identify items via information that is wavelength-encoded within an applied mark, as well as a mark reading/decoding scheme. Ih the perferred embodiment the marks (2) are multi-dimensional. In one preferred embodiment the marks are used to realize multi-dimensional wavelength-enabled coding schemes. The marks (2) can be overlayed one upon another and/or they can contain one or more key regions having at least one predetermined spectral chatacteristic for providing information related at least to reading and/or decoding the marks.
