Holographic interferometry for the study of liquids [PDF]

open access: yesJournal of Molecular Liquids, 2007
Holography is an optical technique enabling to record phase objects. Holographic interferometry uses this faculty to make a phase object interfere with a memory of itself at a preceding time, recorded on a hologram. Interference fringes therefore inform on any variation of the phase of the object.
