Abstract

A method for operating an optical filter in multiple modes. In one embodiment, an optical filter may be operated in a sensitivity mode to thereby generate a white light image representative of a region of interest. The optical filter may then be operated in a specificity mode to thereby generate a hyperspectral image representative of said region of interest. The white light image and the hyperspectral image may be fused to generate a hybrid image that provides morphological and hyperspectral data. The white light image and the hyperspectral image may be generated using a single detector, eliminating the need for image realignment.
