Abstract
A remote substance detection system is provided, the system comprising: at least one light directing element lens; at least one optical multispectral filter; and at least one detector; wherein the optical multispectral filter is configured to have at least one target substance band for detection of at least one target substance and at least one spectral reference band. Also a device and method for remote substance detection is provided.

A remote substance detection system, the system comprising:
- at least one light directing element;
- at least one optical multispectral filter;
- and
- at least one detector;
- wherein the optical multispectral filter is configured to have at least one target substance band for detection of at least one target substance and at least one spectral reference band.
An optical filter comprising:
- one or more filter sections, wherein at least one of the one or more filter sections is a target substance filter section for detection of at least one target substance and at least another one of the one or more filter sections is a spectral reference filter section;
- wherein the optical filter is configured to be disposed in an optical path of a lens and focal plane array, and is configured to filter light that passes through the lens to reach a planar surface of the focal plane array.
A computer-implemented method of designing an optical filter for remote substance detection, comprising the steps of:
- determining at least one target substance band for an optical multispectral filter to be used in a remote substance detection system;
- determining at least one spectral reference band for the optical multispectral filter;
- and
- designing the optical multispectral filter based at least in part on the at least one target substance band and the at least one spectral reference band.
