Abstract:
1. Differential spectrophotometry process, for analysing a non-limpid medium ( 11 ), this process being characterised that: the non-limpid medium is lit by at least one light pulse allowing the subsequent use of the partial derivative, as a function of the wavelength, of at least one spectro-temporal transmission image acquired from the medium thus lit, at least one spectro-temporal transmission image, in counting mode is acquired, through at least one light collector, from the medium thus lit, allowing the subsequent use of the partial derivatives of the image as a function of the wavelength and of the flying time of the light pulse, and the image and its partial derivatives are processed as a function of the wavelength and of the flying time so as to acquire information about the non-limpid medium.
