Adaptive holographic interferometry is a promising method for high-sensitivity phase- modulation measurements in the presence of slow perturbations from the environment. This …
Dynamical holography is an interferometric method that allows the measurements of phase modulations in the presence of environmental low-frequency fluctuations. The technique is …
Self-adaptive holography is an interferometric method in which a Kerr-like medium is used— instead of a beam splitter—to recombine the interfering beams. A Kerr medium is …
Adaptive interferometers based on dynamic holography within a nonlinear medium allow to precisely measuring phase modulations in noisy environments. Thanks to its adaptive …
Two-wave mixing (TWM) via a dynamic hologram recorded in a photorefractive crystal allows the implementation of adaptive interferometers. These interferometers can achieve …
We report the realization of an adaptive holographic interferometer based on two-beam coupling in an optically addressed liquid crystal spatial light modulator operating at 1.55-μm …
