Abstract :
We measured simultaneously blood flow and hemoglobin concentration change in the exposed area of an anesthetized rat using laser speckle patterns acquired at two wavelengths. Blood flow was successfully analyzed in a frame rate. Changes of oxy- and deoxy-hemoglobin concentrations were temporally measured. These results indicate the usefulness of the method.
