Abstract

Summary form only. Time-resolved measurements of the light scattered by a tissue can be useful for the evaluation of optical coefficients and for the resolution of inverse problems. The time resolution required in such measurements is of the order of a few picoseconds. This classically implies expensive and high-tech setups using picosecond lasers and streak cameras or other time-gated techniques. We have shown that such information can be obtained through the analysis of the speckle pattern fluctuations observed when the laser diode source wavelength is modulated.
