Rapid advances have recently been made at SRS Daresbury in optical-detection methods for both micro-imaging x-ray absorption spectroscopy (ODXAS, ODEXAFS), and in the development of volume-integrated synchrotron-laser pump-probe XAS methods (PP-ODXAS). The purpose of the present work is to describe the latest developments that enable these two methods to be coupled, providing micro-imaging of both the transient and CW synchrotron-laser interactions. Examples are provided whereby the distribution of both radiative and non-radiative centres in heterogeneous silicate samples can be mapped and directly correlated with the chemistry and structure of the host lattice.
