Abstract: A method for enhancement of spontaneous Raman scattering (SRS) from gases comprising a multimode blue laser diode which receives feedback from a near concentric bidirectional multipass cavity in such a way as to generate a circulating power of order 100 W for a sample volume of 10 mm3. The feedback, provided via a volume Bragg grating, reduces the laser bandwidth to 4 cm-1. Spectra of spontaneous Raman scattering from ambient atmospheric air, detected collinearly with the pump, were recorded with a limit of detection below 1 part-per-million.

Abstract: A method of determining components present in a sample from spectral data obtained from the sample comprising resolving each of a plurality of models of the spectral data, the plurality of models comprising models having a different number of component reference spectra selected from a set of predetermined component reference spectra; selecting a one of the plurality of models based upon a model selection criterion and determining one or more components present in the sample based upon the selected model. The model selection criterion comprises a measure for each model, which balances improvements in fit quality of the model to the spectral data against a complexity penalty determined from the number of component reference spectrum used in the model.

Abstract: A spectral imaging system comprises: a spatial encoder comprising a first light encoding device comprising a first mask for spatial encoding, the first mask being configured with one or more encoding patterns; a spectral encoder comprising: a dispersion arrangement for splitting spatially encoded light from the first light encoding device into a plurality of components; and a second light encoding device comprising a second mask for spectral encoding of the plurality of components, the second mask having one or more encoding patterns; and at least one single-pixel photodetector positioned to measure light that is encoded by the masks. The spatial encoder is operable to spatially encode light by generating a sequence of different patterns or partial patterns of the one or more encoding patterns of the first mask. The spectral encoder is operable to spectrally encode light by relative movement between the dispersion arrangement and the second mask.

Abstract: A method for monitoring the production of a material (18,20) such as graphene in a liquid dispersion (14) in real time, comprises supplying the liquid dispersion to a fluid gap (106) defined between a first layer (101) and an opposed second layer (102), wherein the first layer (101) is light-transmissive and wherein the second layer (102) has a diffusely reflective surface (102a) facing the first layer. The diffusely reflective surface (102a) is illuminated with light from a light source (210) and light reflected from the diffusely reflective surface is detected at an associated photodetector (220). A light path from the light source to the photodetector comprises the light passing through the transmissive layer (101) towards the diffusely reflective surface (102a) through the fluid gap (106), reflecting off the diffusely reflective surface and passing back through the fluid gap towards and onwards through the transmissive layer. The concentration of the material (18,20) in the liquid dispersion (14) can be determined from the detected reflected light (234). The fluid gap (106) is typically an integral part of apparatus for producing the material, such as being formed between an inner rotor (102) and an outer casing wall (101) of a liquid exfoliation apparatus (100).
