A method is suggested for separating photons coming from different depths of tissue while externally stimulating tissue via infra-sonic vibration. The process of tomographic information extraction using the speckle time multiplexing approach is presented. Use is also made of a modulated laser combining a speckle-pattern tracking method for sensing surface tilting changes with an interferometer for sensing surface z-axis changes at the same scan time.
