Abstract
The spatial spectral interference (SSI) technique is used in order to characterize diffused femtosecond laser pulses and to verify the validity of a new spectral ballistic imaging technique recently proposed. Time-spectrum transform methods are assessed for the duration lengthening measurement of low (snake photons) and forward diffused pulses. Results are shown for water/milk samples in the range of 0.38-2.3 MFP. The discussion is based on the comparison with the non-linear cross-correlation time measurement of pulses. An incoherent source is used in order to confirm the results on a broader spectral range.
