Abstract

We explore in this paper a new method to perform time-resolved measurements of the diffuse light transmitted through a thick turbid medium. This method is based on the analysis of the speckle fluctuations due a wavelength modulated source. A time resolution of about 50 ps is already achieved, and we expect to improve this result soon. This method could allow the design of low cost setups to perform such measurements.
