摘要： Systems and method for detecting unknown samples wherein pattern recognition algorithms are applied to a visible image of a first target area comprising a first unknown sample to thereby generate a first set of target data. If comparison of the first set of target data to reference data results in a match, the first unknown is identified and a hyperspectral image of a second target area comprising a second unknown sample is obtained to generate a second set of test data. If comparison of the second set of test data to reference data results in a match, the second unknown sample is identified as a known material. Identification of an unknown through hyperspectral imaging can also trigger the visible camera to obtain an image. In addition, the visible and hyperspectral cameras can be run continuously to simultaneously obtain visible and hyperspectral images.

摘要： The disclosure is generally directed to a method and apparatus for providing an image of a sample. The apparatus includes an illuminating source for transmitting photons to a sample. The transmitted photons illuminate the sample or are scattered upon reaching the sample. A lens collects the scattered photons and transmits the scattered photons to a tunable filter for forming an image. The illuminating photons traveling from the illuminating source to the sample do not pass through the lens.
