APPARATUS AND METHOD FOR MULTI-SPECTRAL DUAL BALANCED IMAGING

摘要

An apparatus and method for multi-spectral dual balanced imaging is provided. The apparatus includes: (a) a first member operable to produce from incident light a first band having first band wavelengths and a second band; and (b) a second member operable to produce from the second band a third band having wavelengths shorter than the first band wavelengths, excluding the first band wavelengths and having wavelengths longer than the first band wavelengths. The method involves: (a) producing from incident light a first band having first band wavelengths and a second band; and (b) producing from the second band a third band having wavelengths shorter than the first band wavelengths, excluding the first band wavelengths and having wavelengths longer than the first band wavelengths.

1. An apparatus for multi-spectral balanced imaging, the apparatus comprising:
(a) a first member operable to produce from incident light a first band having first band wavelengths and a second band; (b) a second member operable to produce from said second band a third band having wavelengths shorter than said first band wavelengths, excluding said first band wavelengths and having wavelengths longer than said first band wavelengths; (c) a first detector for producing a first image by detecting said first band; and (d) a second detector for producing a second image by detecting said third band after said third band has propagated from said second member to said second detector, wherein a first intensity associated with said first band is substantially equal to a second intensity associated with said third band when said incident light is uniform.
