Abstract

If coherent light is incident upon a whole blood sample, the backscattered light can be recorded, resulting a speckle image. A program was written to extract the time series from each pixel of the CDD conversion matrix. The autocorrelation time of the series was calculated and the autocorrelation time was measured for blood samples of different human subjects. The autocorrelation time was analyzed and compared with the erythrocyte sedimentation rate (ESR) measured during a standard laboratory test using the modified Westergren method. A fast procedure for assessing the ESR is suggested..
