Abstract

This paper describes the development of a specially designed multi-modal microscope system that provides hyperspectral imaging from 300 to 1,700nm with a spatial resolution as high as 1µm in each of its optical measurement modes, i.e. reflectance, transmission, luminescence, and polarisation. The microscope system is fully automated and can handle large area samples from forensic tape-lifts. Demonstration of performance using tape-lift evidence samples that were seeded and studied to mimic real-life crime evidence collections at scene will be shown
