Abstract

Studied a Laser Doppler Flowmetry based on DSP chip TMS320VC5402 to implement the measurement of microcirculation blood flow. Fast Fourier Transform is used to extract the signal frequency under poor signal noise ratio (SNR). And also FFT algorithm is applied to detect the signal frequency by software to improve the operation more flexible and the hardware more simple.
