Improved Spectral Imaging Microscopy for Cultural Heritage through Oblique Illumination

1 Jan 2020Lindsay OakleyStephanie ZaleskiBillie MalesOllie CossairtMarc Walton

This work presents the development of a flexible microscopic chemical imaging platform for cultural heritage that utilizes wavelength-tunable oblique illumination from a point source to obtain per-pixel reflectance spectra in the VIS-NIR range. The microscope light source can be adjusted on two axes allowing for a hemisphere of possible illumination directions... (read more)
