Courbes de visibilité du spectre cannelé

Abstract

A Michelson interferometer is illuminated by a parallel beam of white light. The visibility of the channelled spectrum or spectral density modulation at the exit of the interferometer is measured as a function of the path difference between the two beams formed in the interferometer. The experimental results show that the contrast has not completely disappeared for a path difference much larger than that already reported in the literature.
