Diffractive Optics based on metamaterials

A new technology for producing flat optical components based on optical metasurfaces. These components can potentially serve high resolution imaging, spectrometry, light processing and beam shaping devices. The optical metasurfaces that we develop are composed of closely spaced optical nanoantennas which can be deposited on a wide variety of rigid and flexible surfaces. The engineered nanoantennas […] Read More >

Improvements in BOTDA for fiber optic sensors

TechnologyThis method is based on the Brillouin effect in optical fibers. By using a simple single mode optical fiber, strain is measured in a distributed manner along the entire fiber length, simultaneously, in high repetition rate. By attaching/planting the optical fiber to/in a mechanical structure, its mechanical behavior can be dynamically measured. The Need While […] Read More >

Multi Focus Imaging using Optical Phase Mask

Abstract A method for extended depth of field imaging based on image acquisition through a thin binary phase plate followed by fast automatic computational post-processing is presented. By placing a wavelength dependent optical mask inside the pupil of a conventional camera lens, one acquires a unique response for each of the three main color channels, […] Read More >

Super resolution microscopy based on photo-excited nonlinear reflectivity

A new, label free, far field super resolution scheme, aimed towards material science, which is based on ultrafast, nonlinear excitation of materials to non-equilibrium state. In a pump-probe scheme, we optically excite a spatial temperature profile throughout the diffraction limited spot, and probe the material with an overlapping beam. Due to nonlinearities in thermal properties, […] Read More >

Free online web wizard application to assess the amount of nonlinear interference noise generated in fiber-optic communications systems

Nonlinear interference noise (NLIN) is arguably the most important factor limiting the capacity of fiber-optic communication systems. It is customary to classify nonlinear phenomena as either intra-channel, or inter-channel. Intra-channel effects relate to the nonlinear distortions undergone by each of the WDM channels individually (i.e independently of the data transmitted over other WDM channels), whereas […] Read More >

Using Eye-Tracking in VR to Identify Subject Preferences to Optimize Personalization

The implementation of virtual reality (VR) has been spreading in many research fields and healthcare applications. In order to better personalize the presented content, there is a need to identify the subjective experience at each time point. Previous studies with eye-tracking (ET) have demonstrated its links to preferences; therefore, collecting ET data during VR experiences […] Read More >

Traumatic brain injury (TBI) in a well: a modular three-dimensional printed device for inducing traumatic brain injury in vitro

There is a rapid increase in the prevalence of traumatic brain injury (TBI) with long-term neurological consequences. While this is the number 1 cause of death for kids under the age of 16, and effect more than 1.6 million people annual in the USA alone, there are limited tools that allow to study TBI, as […] Read More >
