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.

Wataru Kamo 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.

Vera Marinova Hybrid light valve device with graphene-based electrodes


We demonstrate a near infrared sensitive light valve device, assembled by Ru–doped BSO crystal and LC layer, using graphene-based electrodes. Modulation characteristics and response time reveal the graphene-based device displays great potential for near infrared applications.

Igor Shevkunov 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.

Shi-Ee Leng 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.
