Abstract
A method to determine an electronic signature characteristic of a fluid medium comprises making a reception surface for receiving the fluid medium on at least one face of the substrate, putting the fluid medium into contact with the reception surface in order to make an interface between the substrate and the fluid medium, lighting at least one zone of the interface through the fluid medium with a pulsed light beam in order to create photogenerated electric charges, using a microwave reflectometer to measure the lifetime durations of the photogenerated electric charges, which durations have respective values that depend on the recombination rate at the interface between the substrate and the fluid medium, creating a matrix of measured lifetime duration values for the photogenerated electric charges, and using the matrix to determine the electronic signature characteristic of the fluid medium.
