Abstract

We demonstrate the use of a wide-field, compact and ultra-stable hyperspectral camera, based on the Fourier-transform approach [1], to investigate the photoluminescence emission occurring from different radiative recombination paths in artist materials and paintings. The camera, based on the translating wedge-based identical pulse encoding system (TWINS), is characterized by high spectral resolution, high flexibility and compactness. Thanks to these latter feature we show how the device can be easily adapted for both microscopy measurements and remote time-gated imaging of paintings and we show its use for the identification and mapping of fluorescent species in artworks by also exploiting the potentiality provided by chemometrics methods.
