1. A method comprising:

  • obtaining an optical image representative of a sample scene wherein said sample scene comprises at least one target material;

    acquiring spectroscopic data representative of a first target material in said sample scene wherein said spectroscopic data comprises at least one spectrum representative of said first target material;

    selecting a first spectroscopic band of interest and a second spectroscopic band of interest from said spectrum representative of said first target material;

    obtaining a ratio of said first spectroscopic band of interest and said second spectroscopic band of interest;

    comparing said ratio to a range of threshold values; and

    based on said comparison, displaying a result wherein said result comprises a first pseudo color overlay on said optical image, and wherein said first pseudo color overly is obtained by assigning a first pseudo color to said first target material and wherein said first pseudo color corresponds to at least one of;

    a known material and a class of known materials.
