Evaluation of skin blood flow using laser speckle phenomena (VII)

This is the authors' abstract. We don't add key points for this paper.

Theoretical analyses are conducted on the probing volume of a laser speckle flow monitor. The level of the light backscattered from scattering centers at certain depth in the skin tissue to the detecting point is evaluated. It is found that the size and the depth of the probing volume becomes larger with an increase of the distance between the illuminating and detecting fibers.
