Abstract

In this paper, we describe a technique for elasticity and depth measurement via both secondary speckle and time multiplexing interference approach. Using external stimulation of elastic medium (in example: human tissue) by infra-sonic vibration, photons from different depths of the elastic medium were separated. In addition, this work uses a modulated laser that incorporates at the same scanning time, a speckle pattern tracking method for sensing surface tilting and interferometer method for sensing z-axis movements. In this paper, we present preliminary experiments showing the ability to separate data of light coming from different layers in the elastic medium.
