Abstract

Multispectral measurement configurations are proposed as alternative tools for on-line moisture assessment for materials or parts on conveyers. In a first imaging configuration combining high speed Short Wave Infrared Range (SWIR) linear camera and lasers used as backlighting sources, images are acquired in several spectral bands and further processed to enhance information related to moisture level of pharmaceutical capsules. A second scanner architecture, based on a rotating polygonal mirror and an infrared multispectral fibered source operated in the SWIR spectral range, is also proposed to map water content of diffuse materials. Qualitative imaging and measurements capability of both configurations have been investigated in laboratory or in representative sorting machine environment.
