Abstract:
An optical chemical analyser comprises a source of a first amount of radiation ( 46 ), an optics module configured to direct the first amount of radiation such that it is incident on or passes through a target ( 14 ) at a target location, the optics module further being configured to receive a second amount of Raman scattered radiation from the target and direct the second amount of radiation ( 206 ) to a Spatial Interference Fourier Transform (SIFT) module, the SIFT module including a first dispersive element ( 216 ) and a second dispersive element ( 218 ), the SIFT module being configured such that a portion of the second amount of radiation is received by the first dispersive element and interferes with a portion of the second amount of radiation received by the second dispersive element to form an interference pattern; the SIFT module further comprising a detector ( 48 ) configured to capture an image of at least a portion of the interference pattern and produce a detector signal ( 226 ) based on the captured image; and a processor configured to receive the detector signal from the detector and perform a Fourier transform on the detector signal to thereby obtain a frequency spectrum of the second amount of radiation.

Claim (Index 18):
An optical chemical analyser according to  claim 17 , further comprising a first optical filter located at a first end of the optical fibre and a second optical filter located at the second end of the optical fibre, wherein the first optical filter is selected from the group consisting of an optical band pass filter, an optical band stop filter and an optical edge filter; and wherein the second optical filter is selected from the group consisting of an optical band pass filter, an optical band stop filter and an optical edge filter; and wherein the first and second optical filters are configured to receive radiation and orientated such that an optical axis of each of the first and second optical filters is non-parallel with respect to an optical axis of the received radiation.
