Abstract
A two-dimensional Fourier compression method has been developed as a t ool for portable sensors. Ion mobility spectrometry (IMS) yields an ad vanced chemical sensor for monitoring trace quantities of compounds in air. Two-dimensional Fourier compression can increase the compression efficiency without compromising the quality of compressed data. A cri terion for the automatic determination of the compression efficiency o r cutoff frequency has been developed and evaluated with IMS data. IMS data were compressed by 97% without significant loss of information.
