Abstract
A non-intrusive and non-contact near infrared acquisition system based on a PGP spectrometer is presented. This work is an extension to the whole near infrared range of the spectrum, from 1000 to 2400 nm, of a previously designed system in the Vis-NIR range (400-1000 nm). The reason under this investigation is to improve material characterization and material classification performance. To our knowledge, no imaging spectroscopic system based on a PGP device working in this range has been previously reported. The components of the system, its assembling, alignment and calibration procedures will be described in detail.
