摘要： The invention relates to a measuring arrangement for an optical spectrometer, in particular a photon density wave (PDW) spectrometer. The measuring arrangement comprises a plurality of optical waveguide elements (20), each of which extending along a longitudinal direction (24) from a proximal end (22) to a distal end (23), the distal end (23) configured to be placed in a substance to be measured. The optical waveguide elements (20) are configured for receiving excitation light from a light emitting device at the proximal end (22) and for emitting the excitation light into a substance to be measured at an outlet (21) at the distal end (23). They may further be configured for receiving measurement light caused by excitation light emitted into the substance and for conducting the measurement light towards the proximal end (22) to a detection device. The outlet (21) of the optical waveguide elements (20) are formed laterally relative to the longitudinal direction (24) such that excitation light is emitted from the outlet (21) in an emitting direction (25) transverse to the longitudinal direction (24) and/or measurement light is received in a receiving direction (25) transverse to the longitudi- nal direction (24). The outlets (21) may be arranged in at least two groups to form at least two sensing zones for measuring a substance in at least two distinct measuring spaces around the sensing zones.

摘要： A stimulated Raman scattering spectrometer for real-time, high- resolution molecular analysis of gases is based on two hollow-core fibres (420, 450) illuminated by a single high-power, short-pulse laser pump. The first fibre (420) is prefilled with high-concentration target gases. Interaction of each target gas inside the first fibre (420), with the laser pump, generates Raman signals corresponding to the target gases. The combined beam of the Raman signals and the pump laser beam is directed into the second fibre (450) containing the measured target gases. Interaction of each target gas with the combined beam generates the Stimulated Raman Growth, i.e., amplification of the Raman signal, which is proportional to the corresponding target gas concentration. A receiver subsystem (30) receives the beam from the second fibre (450), spectrally separates it to wavelengths corresponding to each target gas, extracts the Stimulated Raman Growth value corresponding to each target gas and calculates the concentration of each target gas.

摘要： Examples of this application disclose a method for measuring optical properties of a target. The method comprises illuminating the target with an illumination area with a display screen in contact with the target, and analysing signals reflected from the target and transmitted back through the display screen to a sensor positioned behind the display screen, to determine the optical properties of the target.
