Abstract

Mini Raman spectroscopy is applied to rapid extraventricular substance identification. Aiming at its outdoor application a particular system design of spectral data acquisition and processing was presented. A novel spectral data acquisition technique with CCD of which the integration time is controllable and self-adjusting was realized. A portable power management design was introduced. ARM and CPLD techniques were combined to implement real-time control and data processing. A program of searching the peak of Raman spectra based on comparison algorithm was given.
