Methods for increasing measurement sensitivity by using waves reconstructed from a hologram in higher diffraction orders and from a re-recording of a hologram are considered. A review is given of methods for increasing sensitivity during the multiple passage of a beam through a volume being investigated or a hologram. A review of the use of holographic interferometry with increasing sensitivity for transparent media diagnostics is given.
