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.

Spectrophotometric camera

A spectrophotometric scanner suitable for producing spectral reflectance images of surfaces of samples for a plurality of wavelength bands is disclosed. The spectrophotometric scanner comprises a scanner head for collecting spectral reflectance data, a positioning mechanism for positioning the scanner head in relation to a surface, and a computing device for controlling the mechanism and recording and analyzing the spectral reflectance data. The computing device directs the positioning mechanism to position the scanner head on a row of locations in a grid of locations of the surface; directs the scanner head to measure spectral reflectance data for each location in the row of locations; records and analyzes the spectral reflectance data; and produces spectral reflectance images from the spectral reflectance data. A light source in the scanner head comprises a plurality of sequentially controllable LEDs, each producing light in a different wavelength band.
