APPARATUS AND METHOD FOR MULTI-SPECTRAL DUAL IMAGING

摘要

A multi-spectral dual imaging apparatus producing, from incident electromagnetic energy, a plurality of separated beams of electromagnetic energy respectively associated with distinct wavelength ranges for delivery to an image capturing device includes first directing means for directing at least a first portion of the incident electromagnetic energy along a first path between an entrance of the apparatus and the image capturing device; first filtering means for filtering electromagnetic energy being directed along said first path; second directing means for directing at least a second portion of the incident electromagnetic energy along a second path between said entrance and the image capturing device; second filtering means for filtering electromagnetic energy being directed along said second path, wherein said first directing means reflects electromagnetic energy being directed along said first path an odd number of times greater than said second directing means reflects electromagnetic energy being directed along said second path.
