In this work we present a novel hyperspectral camera based on a compact birefringent interferometer to perform reflectance measurements on works of art.
The innovative aspect emphasized in our system lies the capability to acquire hyperspectral images of the sample at different magnification, allowing to image a field of view ranging from few millimetres to tens of centimetres.
With our work, we want to demonstrate the effectiveness of this system when performing hyperspectral imaging of painted surfaces at the macro scale, i.e., with few millimetres of field of view, and discuss its potential to resolve the details of a painting as pigments’ grains.
