Dynamic Monitoring of Sensitivity of Materials to Light/Radiation (microfade testing and mitigation of radiation induced alteration)
A sensitive dynamic monitoring method to assess reflectance alterations for microfade testing of material sensitivity to light exposure, and the method can also be used as a monitoring method for the detection of both physical and chemical changes on historical material surfaces induced by intense radiations (e.g. lasers, synchrotron X-rays) used for material analysis.

Hybrid OCT @ 1350nm & Microscopic VIS/NIR Spectral Imaging (415-845 nm)
The Hybrid system combines optical coherence tomography (OCT) system with a reflectance spectral imaging system into one instrument. OCT provides 2D and 3D virtual cross-sectional images in a non-invasive and non-contact way. It is suitable for the investigation of translucent and transparent materials (e.g. varnishes, glass, glazes) in the near-infrared (central wavelength 1350 nm). VIS-NIR Spectral Imaging can provide identification of materials. The simultaneous use of the two analysis methods allows for a 1:1 spatial alignment between the spectral images and OCT 3D volumetric data sets, providing additional context on the layer structure.

Long Wavelength OCT @ 1960 nm
Long Wavelength Optical Coherence Tomography (OCT) provides 2D and 3D virtual cross-sectional images in a non-invasive and non-contact way. It is suitable for the investigation of surface and subsurface translucent and transparent materials (e.g. varnishes, glass, glazes) in the short-wave infrared (central wavelength 1960 nm) with a resolution of a few microns. This OCT is optimised to provide a larger penetration depth in materials than OCTs at shorter wavelength making it more suitable to the investigation of more scattering materials such as paints and enamels.

Remote to Close Range Laser Induced Breakdown Spectroscopy (LIBS)
Laser-induced breakdown spectroscopy (LIBS) is a micro-destructive technique that gives elemental analysis of materials through analysing the plume created by ablation of the material by a high intensity laser beam focused to a spot <1mm. LIBS is sensitive to nearly all elements. Remote LIBS allows the analysis of monuments and objects from distances up to tens of metres. It is especially suited to applications on architectural and archaeological sites.

Remote to Close Range Laser Induced Fluorescence Spectral Imaging (LIF)
Laser induced Fluorescence spectroscopy (LIF) can be used to complement other spectroscopy techniques such as XRF and reflectance spectroscopy to identify and characterise materials. LIF hyperspectral imaging at standoff distances of up to tens of metres can be used to conveniently analyse any area on a monument/object from the ground level without having to move the instrument. It can also operate at close range to give microscopic fluorescence spectral images.
