Abstract
A spectrophotometric camera and method for measuring spectral energy in different wavelength bands at a plurality of locations are disclosed. The spectrophotometric camera comprises: a light source for sequentially producing light in different wavelength bands; an imaging device containing an array of sensors for detecting light at a plurality of locations; and a reference detector and an adjusting device for adjusting the light detected by the array of sensors. Spectral reflectance data from each of the plurality of locations on the surface of a target for each wavelength band in the plurality of light wavelength bands is measured. Spectral reflectance images are created, and features are extracted from the spectral reflectance images.
