Abstract
This paper describes a polarised Short Wavelength Infra-Red (SWIR) system using Commercial Off-The-Shelf (COTS) technology, which was assessed against a variety of tripwires and backgrounds during night and day trials as part of a DSTL (UK) programme. The system comprises a polarised SWIR illuminator and cameras fitted with SWIR filters and polarisers. Various image-processing techniques were developed and evaluated including Stoke's S1 parameter, the Radon Transform and a novel and robust feature detector. Within the limits of the optical system, a tripwire recognition capability in vegetation was achieved that approached that of a human.
