发明名称 IMAGERIE TOMOGRAPHIQUE PAR MICROSCOPE INTERFEROMETRIQUE A IMMERSION
摘要 A device for the tomographic imaging of an object to be analyzed, the device comprising a light source that emits a light beam with a coherence length substantially equal to the thickness of a slice of the object to be analyzed; and an interferometric imaging system comprising at least one objective, a reference mirror and a light-beam splitting means; wherein the interferometric system is arranged so that the objective defines a first focusing plane at the slice of the object to be analyzed and a second focusing plane at the reference mirror, and wherein the interferometric imaging system comprises at least a first compensating medium positioned between the second focusing plane and the splitting means, the thickness and the optical index of the at least one compensating medium having optical properties such that a first optical path of the light beam emitted from the light source between the first focusing plane and the splitting means is substantially equal to a second optical path of the light beam between the second focusing plane and the splitting means and such that a first dispersion between the first focusing plane and the splitting means is substantially equal to a second dispersion of the light beam between the second focusing plane and the splitting means.
