Abstract: An imaging apparatus includes a camera with a solid-state sensor and an illumination selector. The illumination selector is arranged for optical coupling with the sensor and arranged for communicating electromagnetic radiation within a shortwave infrared narrowband to the sensor. The shortwave infrared narrowband includes a peak absorption or peak reflection wavelength of moisture to infrared illumination to image moisture disposed within a solar cell array.

Abstract: A method of determining the composition of a polymeric body includes applying electromagnetic radiation to the polymeric body, modulating the electromagnetic radiation using a tagant disposed within a polymer composition forming the polymeric body, and receiving the modulated electromagnetic radiation from the tagant at an infrared detector. The electromagnetic radiation received from the tagant has a signature corresponding to the polymer composition forming the polymeric body. A method of making a polymeric body and system for determining composition of a polymeric body are also described.
