  1. Visualizing Growth In Hyperspectral Imaging: A Q&A With TruTag CTO Hod Finkelstein

    Dr. Finkelstein discussed with Photonics Online how his experience in the medtech and RF industries helped inform decisions when creating new HSI technologies. He offered insight into maintaining balance in the growth of both optical and data processing technologies for HSI, and discussed development of TruTag’s Prism Award-winning hyperspectral imaging solution.

  2. Perceptions In Autonomous Driving: Embedding A Multi-Sensor Solution Into A Single Microcontroller Platform

    Autonomous driving systems are beginning to make their mark in the world, but questions still remain concerning everything from how different their embedded sensor and perception technologies work together, to how safe these systems really are. These are the types of questions that the LETI research institute of CEA Tech attempted to address when creating its sensor fusion solution intended for autonomous driving applications. This Q&A with a LETI research engineer, Julien Mottin, addresses the SigmaFusion solution, the processes and challenges involved in its design, and the rationale behind embedding it into the AURIX microcontroller platform.

  3. Behind The Curtain: Developing The First Laser Based On Bound States In The Continuum (BIC)

    Nearly 90 years after physicists John von Neumann and Eugene Wigner predicted that certain wave states are able to remain perfectly confined, or bound, in an open system, this wave physics phenomenon - called bound states in the continuum (BIC) - has been demonstrated by researchers at the University of California (UC) in San Diego in the form of the world’s first BIC laser. This Q&A discusses the design process and unique features of this lasing technology, as well as future steps in making BIC lasers electrically powered and how long it might take to build a BIC laser to the desired specifications.

  4. Driving Metamaterial Motion With Light: A Q&A With UCSD’s Prof. Ertugrul Cubukcu

    Light is considered a driving force for countless innovative and maturing technologies, such as solar cells, lasers, microscopy, and spectral imaging. Unfortunately, light has always ridden “shotgun” next to the optical components controlling the application. So, what would happen if we considered light as the literal “driver” of a device’s movements? This article covers new technology for an instrument made from a plasmomechanical metamaterial that is capable of using a constant light source to manipulate its mechanical properties.
