Holographic augmented reality : towards near-to-eye electroholography via guided wave acousto-optics
Near-to-eye displays act to directly project imagery into a viewer's eye and can range in instantiation from extremely simple (such as an optical viewfinder) to more complex immersive displays for applications in virtual and augmented reality. Many current schemes for near-to-eye display employ …

Multiple plane wave analysis of acousto-optic diffraction of Gaussian shaped light beams
A short history of acousto-optics research is presented along with a general description of how light and sound interact. The Multiple Scattering model is derived and used with a Gaussian light beam to observe the distortion in light beam profile within the sound field. Numerical results are …

Dynamical tuning of phonon transport for information and energy control
… optical coupling, we develop a model of inverse acousto-optics (tuning the speed of sound with optical intensity) and dynamical phonon localization.

High quality integrated LiNbO3 acousto-optic platform for visible light spectrum
… light source, has accelerated the development of acousto-optic platforms (AlN, GaN, Quartz, LiNbO3) for many practical applications such as beam steering, signal processing, and intensity modulation. The recent integration of on-chip acousto-optic devices with photonic integrated circuits lead to …

Real-Time Image Processing Using Acousto-Optic Bragg Diffraction
Optical image processing systems using an acousto-optic cell have been studied previously. However, these previous studies have been limited to two diffracted order in the Bragg regime and two spatial dimensions. Some comparisons between experimental data and theoretical predictions have been made. …

Advanced Prototypes of the Aerosol Limb Imager
… The instrument pairs an extended range acousto-optic tunable filter with a liquid crystal polarization rotator to capture spectrally resolved polarimetric imagery of the atmospheric limb. These technologies provide the capability to extract particle size information from the sampled …

The study of acoustic properties of P205-doped silica fiber
Silica-based optical fibers have been applied to numerous fields. The interactions between acoustic phonons and the optical wave are involved in several of these applications. A significant stimulated scattering mechanism observed is stimulated Brillouin scattering (SBS), resulting in strong …
