Abstract

We present a lateral laser speckle contrast analysis method combined with line beam scanning illumination to improve the sampling depth of blood flow imaging. Both the phantom and animal experimental results suggest that localized illumination and lateral speckle contrast analysis can significantly enhance the deep blood flow signal to improve the sampling depth of laser speckle contrast imaging compared with the traditional full-field illumination laser speckle contrast analysis method.
