Patent ID: 6940602

Claim:
An interferential microscopic imaging method of an object ( 9 ) wherein: a beam ( 2 ) coming out of a light source ( 1 ) is sent to each of the arms of a two-wave interferometer, one ( 7 ) of the arms comprising an object ( 9 ), continuous phase variation in the interference signal (S) is introduced, consisting of a sine wave modulation of frequency f, the interference signal (S) is integrated during this phase variation by means of a multichannel detector ( 15 ), characterised in that: the modulation of the interference signal (S) results from the mechanical oscillation of a set of elements ( 16 ) of the interferometer and has an amplitude ψ and a synchronisation phase θ, the multichannel detector ( 15 ) operates at a frequency f′ so that f′=n f, n being an integer and greater than or equal to 2, the integration of the interference signal (S) takes place during fractions 1/n of a modulation period, the integrated interference signal is processed digitally in order to calculate an image.
