Abstract :
This paper discusses the incorporation of a novel method of signal processing with a MEMS Raman-based chemical/biological sensor. The method utilizes an absolute sum-difference calculation performed on the FFT of a periodic Raman signal that will be obtained from the MEMS sensor. The result of the sum-difference calculation is used in a threshold determination of the presence of an analyte of interest.
