Summary on Grant Application Form
At St Andrews University, we have made a proof of principle demonstration of a compact Fourier-transform spectrometer with no moving parts. The operating principle relies on birefringement materials to introduce a spatially varying path difference between orthogonal polarisations of the incoming light. The use of a detector array to record the spatial extent of the interferogram means that the spectrometer can be operated with pulsed or rapidly varying light sources. Within this LINK project (Siemens (UK), British Gas, Drager (UK), Halbo Optics and Shell (UK) we will extend the techniques with view to the detection of airborne pollutants. The aim is to produce a new range of low-cost research will be directed at spectral convolution and recognition in the Fourier domain, thereby eliminating the need for micro-processor control.
