We show that spatially resolved backscattering can be used for simultaneous measurements of static and dynamic properties of highly turbid media. The spatial variation of the backscattered intensity gives access to the transport mean free path. The decay of the temporal intensity-intensity correlation function depends on the point of observation. This property can be used to probe complex dynamics with several time scales. The implementation of the method and the data analysis are tested on concentrated suspensions of polystyrene spheres.
