Results in Physics, 2021 We propose a simple common-path off-axis interferometric system to perform high-quality quantitative phase imaging based on a rotatable birefringent prism that is placed at the output port of a conventional transmission or reflection microscope.

Digital holographic tomography based on spectral interferometry [PDF]
Optics Letters, 2007 A digital holographic tomography system has been developed with the use of an inexpensive broadband light source and a fiber-based spectral interferometer. Multiple synthesized holograms (or object wave fields) of different wavelengths are obtained by transversely scanning a probe beam.

Elasticity measurement using holographic interferometry double exposure technique [PDF]
, 2004 Holographic measurement of modulus elasticity was performed on samples of aluminum can. It is based upon the measurement of the displacement as a function number of fringes appeared on the body of the loaded can.

Towards Reduced CNNs for De-Noising Phase Images Corrupted with Speckle Noise
Photonics, 2021 Digital holography is a very efficient technique for 3D imaging and the characterization of changes at the surfaces of objects. However, during the process of holographic interferometry, the reconstructed phase images suffer from speckle noise.

Imaging velocities of a vibrating object by stroboscopic sideband holography [PDF]
, 2012 We propose here to combine sideband holography with stroboscopic illumination synchronized with the vibration of an object. By sweeping the optical frequency of the reference beam such a way the holographic detection is tuned on the successive sideband ...
