Title
(EN) APPARATUS AND METHOD FOR MULTI-SPECTRAL DUAL BALANCED IMAGING
(FR) APPAREIL ET PROCÉDÉ D'IMAGERIE À DOUBLE ÉQUILIBRÉ MULTISPECTRALE
Abstract
(EN)
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.

L'invention concerne un appareil et procédé d'imagerie à double équilibré multispectrale. L'appareil comprend : (a) un premier élément servant à produire à partir de lumière incidente une première bande ayant des longueurs d'ondes de première bande et une deuxième bande ; et (b) un second élément servant à produire à partir de la deuxième bande une troisième bande ayant des longueurs d'ondes plus courtes que les longueurs d'ondes de première bande, excluant les longueurs d'onde de première bande et ayant des longueurs d'ondes plus longues que les longueurs d'ondes de première bande. Le procédé consiste : (a) à produire à partir de lumière incidente une première bande ayant des longueurs d'ondes de première bande et une deuxième bande ; et (b) à produire à partir de la deuxième bande une troisième bande ayant des longueurs d'ondes plus courtes que les longueurs d'ondes de première bande, excluant les longueurs d'onde de première bande et ayant des longueurs d'ondes plus longues que les longueurs d'ondes de première bande.
