A method of calibrating a fibre-optic Raman spectroscope system 20 comprising a laser source 21, a spectroscope 30 and a fibre-optic probe 11 to transmit light from the laser source to a target and return scattered light to the spectroscope, comprises transmitting light from the laser source to a standard target having a known spectrum, recording a calibration spectrum of the scattered light from the standard target, comparing the known spectrum and the calibration spectrum and generating a transfer function, and storing the transfer function. The transfer function is then used on further spectral measurements using the spectroscope system. A method of estimating laser power in the system and a method of subtracting a background signal from a Raman spectrum is also disclosed. |
