摘要：
A fast Laser-Doppler flowmetery (fLDF) modified from a commercial one to measure the pulsatile microcirculation in rats. The time constant (TC) of the integrator in the analogy circuit of the LDF was modified; the frequency response of the modification was simulated by PSPICE to estimate the high 3dB frequency. The coefficients of variance (CV) of 32 2-secod ensembles of flux in the calibration standard measured by the commerical LDF and the modified one were less than 2%. The animal tests also clearly demonstrated the pulsatile microcirculation on the renal cortex in the rat.
