Multifunctional laser speckle imaging. [PDF]

Biomed Opt Express, 2020
We have developed a multi-functional laser speckle imaging system, which can be operated in both the surface illumination laser speckle contrast imaging (SI-LSCI) mode and the line scan laser speckle contrast imaging (LS-LSCI) mode.
