Investigation of traveling acoustic waves with digital holography
This paper describes recent advances in high-speed holographic imaging; especially we focus on the use of such an approach to investigate traveling acoustic waves. Special attention considers the case of waves propagating after a shock and in an acoustic black hole.

Digital Holographic Microscopy for Quantitative Observation of Birefringent Material in Biological Samples
Digital holographic microscopy (DHM) provides both amplitude and quantitative phase images. We developed a DHM system specific for birefringence imaging by introducing a polarization selection scheme. We demonstrate the possibility of extracting the complete Jones matrix from birefringent crystals and discuss the possibility of employing this approach for biological targets.

High resolution phase-shift holography
Simplified method of implementation of high
resolution phase shifting holography with use of a rotating
plane-parallel plate is presented. High resolution is achieved by
managed imposing of two effects: phase delay in rotatable
plate and shift of the angled wave front.

Light-Driven Wide-Range Nonmechanical Beam Steering and Spectrum Scanning Based on a Self-Organized Liquid Crystal Grating Enabled by a Chiral Molecular Switch
In this letter, we proposed a beam steering devices bt dye-doped cholesteric liquid crystal with a fingerprint texture. And these devices are optically tunable and reversible based on trans-cis isomerization. In addition, the scanning wavelength can be tuned from 472nm to 713nm.
