Abstract :
A brief introduction of the principle of correlation detection is present in this paper. As portable field-test equipment, an optical densitometer is designed with correlation detection technology to increase detection precision. In the process of designing, cross-correlation is applied to extract weak signal from strong noise. Simulation result with MATLAB shows that the correlation detection processed good performance in this application.
