Abstract: A system and method for multi-spectral gas concentration analysis that includes using a library of multiple sets of optimized spectral sensitivities prepared in advance, and a multi-spectral IR gas analyzer tuned to a set of optimized spectral sensitivity. The multi-spectral IR gas analyzer measures spectral absorption of gas using one or more different sets of optimized spectral sensitivities.

Abstract: A method and system of calibrating multispectral images from a camera on an aerial vehicle, the method including: capturing multispectral images of an area at a plurality of intervals with a multispectral imaging camera; simultaneously or at an arbitrary time capturing sunlight radiance data for each of the captured images; correlating the images with the sunlight radiance data; and calibrating the multispectral images based on the sunlight radiance data to normalize the multispectral images to one or more previous images of the area.

Abstract: A method for determining a custom power spectral distribution (PSD) for use in a specialized light source and a lighting system. The method includes obtaining a PSD corresponding to light that is output by the lighting system, obtaining a constraint, and determining the custom PSD by optimizing (minimizing or maximizing), subject to the constraint, an evaluation function comprising the PSD, an unwanted light function, a wanted light function, or another characteristic function.
