Remote LIBS and Raman imaging for assessment of cultural heritage

Abstract

In this paper, we propose to perform remote laser-induced breakdown spectroscopy (LIBS) and Raman imaging of historical monuments to assess the state of a building. The lidar system is equipped with a Nd:YAG pumped optical parametrical oscillator (OPO) system, allowing laser radiation in the wavelength range 220 nm-4 mum. The laser radiation can be sent through a roof-top dome which can steer the radiation onto the point of interest
