In the past ten years, there has been a lot of research into on-chip spectrometers with customized spectral ranges and small sizes. When splitting various frequencies, there is a trade-off between resolution and size because the propagation length usually scales inversely with the frequency resolution. On-chip compressive spectrometers can be used with scattering media in [..]

Integrating a light source inside a Lab-on-a-Chip (LOC) platform has always been as challenging as much as an appealing task. Besides the manufacturing issues, one of the most limiting aspects is due to the need for an energy source to feed the light emission (battery free). A solution independent of external energy sources can be [..]

Researchers have shown that quantum particles can carry an unlimited amount of information about things they have interacted with. The results could enable far more precise measurements and power new technologies, such as super-precise microscopes and quantum computers. Metrology is the science of estimations and measurements. If you weighed yourself this morning, you’ve done metrology. [..]

Law enforcement and intelligence agencies worldwide have implemented a ground-breaking facial recognition system powered by artificial intelligence that can recognize people wearing masks. In addition, the device can identify people in very dim lighting. The biometric system can identify individuals using only 40% of their face compared to a reference image or video, making it [..]

Engineers have introduced a new technique for performing high-level neural network computations by substituting a photonic tensor core for existing digital processors such as GPUs. In the approach, light-speed energy replaces electricity, and optical processing data feeds at a two to three orders higher performance than an electrical tensor processing unit (TPU), supporting unsupervised learning [..]

Imaging chemical species using mid-infrared light is a key bioimaging and environmental monitoring technique. Still, the mid-IR detectors needed for the task have tended to be expensive, complex, and relatively inefficient. Current mid-IR cameras are based on low bandgap semiconductor materials that require cryogenic cooling to reduce thermally excited electronic noise, and electronically cooled alternatives [..]

The therapeutic management of dry age-related macular degeneration (dry AMD) is difficult. It is one of the main reasons for progressive blindness, depriving millions of people over 65 of their central vision, and it frequently makes it difficult for patients to read, drive, and recognize the faces of their loved ones. Although vitamin-based supplements might [..]

An advanced imaging technique called scanning transmission electron microscopy (STEM) has provided scientists with rough pictures of enamel crystallites. However, the intensity of traditional STEM beams required for a clearer view would damage the enamel before a picture could be generated. In new research, a team used advanced imaging techniques to produce a picture of [..]

Due to limitations in how it can sense objects using lidar, a self-driving vehicle struggles to distinguish between a toddler and a brown bag that abruptly appears in view. The autonomous vehicle business is looking into “frequency modulated continuous wave” (FMCW) lidar to address this issue. Researchers have developed a method for lidar that uses [..]

Displaying three-dimensional pictures that are visible to the unaided eye is best done with 3D holograms. Metasurfaces made of subwavelength structures have a lot of potential for manipulating the light field, which is beneficial for beating the limitations of conventional computer-generated holography. However, issues like low frame rate and low frame number have long stood [..]

Researchers are using cutting-edge microscale accuracy to track the development of coatings as they dry. Thin film coatings accomplish much more than beautifying surfaces. For instance, they can be used as medical equipment in edible films transporting medications to combat the opioid epidemic. For films used in drug delivery technology, it is particularly crucial to [..]

Researchers have shown that a novel near-infrared spectroscopy-based mapping method can differentiate between fat and muscle tissue in the heart. This distinction is crucial when using radiofrequency ablation to address the serious heart rhythm issue known as ventricular tachycardia. The only therapy for ventricular tachycardia is radiofrequency ablation, which involves locating the parts of the [..]

Various 3D sensing, imaging, illumination, and ranging uses, as well as their convergence in new lidar technology, could be made possible by implementing optical phased arrays (OPAs) in integrated photonic circuits. Although large aperture sizes are required to enable medium- to long-range lidar, current integrated OPA approaches must be scaleable regarding control complexity, power consumption, [..]

Researchers have conducted a ground-breaking operation to show “hybrid” quantum networking, which is a first for the world. The method, which combines two ways of encoding information in light particles called photons, may enable more powerful and reliable computing and communications. Quantum networking systems can encode information as discrete variables (DVs) in particles or continuous [..]

A group of researchers has advocated for the use of UV light as a ‘particularly efficient, easily deployable, and economically affordable’ means to limit the spread of coronavirus. The study, involved experts in the fields of virology, immunology, aerosols, architecture, and physics, analyses the possible methods to prevent Sars-Cov-2 propagation in indoor spaces. Small indoor [..]

Advanced nuclear magnetic resonance (NMR) spectroscopy pulse sequence editing enables noninvasive assessment of the spatial distribution of chemical composition and diffusion behavior of materials.
