Mandibular

In order to plan a dental implant operation and the implant size and position, dentists need to know the exact location of the mandibular canal, a canal located in both sides of the lower jaw that contains the alveolar nerve. The lower jaw is an anatomically complex structure and medical experts use X-ray and computer [..]

Optical Frequency Combs

In our information society, the synthesis, distribution, and processing of radio and microwave signals are ubiquitous in wireless networks, telecommunications, and radars. The current tendency is to use carriers in higher frequency bands, especially with looming bandwidth bottlenecks due to demands for, for example, 5G and the “Internet of Things.” ‘Microwave photonics,’ a combination of [..]

3D Holographic Projection

The three-dimensional (3D) vectorial nature of electromagnetic waves of light has not only played a fundamental role in science but also driven disruptive applications in optical display, microscopy, and manipulation. However, conventional optical holography can address only the amplitude and phase information of an optical beam, leaving the 3D vectorial feature of light completely inaccessible. [..]

Computer Vision Technology

Will automated infection tracking become standard procedure in airports around the world? Real-time thermal monitoring combined with biometric data that could be immediately extracted and analyzed (using computer vision technology) would help airport personnel quickly identify individuals with potential illness in even the most crowded terminals. Possible points of contact with the individual could also [..]

X Ray Fluorescence Microscopy

Synchrotron x ray fluorescence microscopy can be used as a method for measuring the concentrations of different elements in cross-sections of the ear at extremely high resolution. This method could be of great importance for addressing many open questions in hearing medical diagnosis research. X ray fluorescence microscopy uses synchrotron radiation to evoke emissions from [..]

Optical Transistors

Leading research groups in the field of nanophotonics are working toward developing optical transistors – key components for future optical computers. These photonic devices will process information with photons instead of electrons, thus reducing the heat and increasing the operation speed. However, photons do not interact with each other well, which creates a big problem [..]

UV Light

The number of COVID-19 cases has not yet hit its peak and supplies of essential personal protective equipment (PPE) such as N95 masks are dwindling, so medical communities are desperately looking for alternative solutions for disinfecting masks that healthcare workers are being forced to reuse. Medical optics solutions can prove very helpful in such conditions.  [..]

Interferometer Sensor

Researchers are now developing a laser-based interferometer sensor that detects coronavirus at the earliest point of infection from a saliva or nasal swab in minutes. The scientists are developing a new rapid, noninvasive optical biosensor demonstrator that will detect COVID-19 in humans as soon as it is present in the body. With the ability to [..]

Diamond Raman Laser

Lasers that emit light at the sodium line (actually a doublet) at a wavelength of about 589 nm are used to produce artificial “guide stars” in the mesosphere at an altitude of around 90 km for use with adaptive optical (AO) systems integrated with large ground-based astronomical telescopes. These artificial stars allow astronomers to use [..]

Lung Tumors

People who are at high risk of developing lung cancer, such as heavy smokers, are routinely screened with computed tomography (CT), which can detect tumors in the lungs. However, this test has an extremely high rate of false positives, as it also picks up benign nodules in the lungs. Researchers have now developed a new [..]

Phase Contrast Imaging

Propagation-based phase-contrast CT (PB-CT) is an advanced X-ray imaging technology that can generate higher quality diagnostic breast images than absorption-based CT (AB-CT), at a glandular radiation dose comparable to, or lower than, conventional mammography and digital breast tomosynthesis (DBT). The technology is currently limited to use with synchrotron light sources, but the evolution of compact [..]

Electronic Skin

As the environmental toll of plastic microparticles and nanoparticles has grown ever more apparent, the possible impact of plastic films in optoelectronic devices has started to raise concerns. A research team now offers one possible answer: Make the films out of fish scales. The team zeroed in on the transparent plastic films used in a [..]

Visible Light Communication

Vehicle-to-vehicle (V2V) positioning is an essential research for the security of autonomous vehicles. Due to low cost and easy accessibility, global positioning system (GPS) has been a popular solution. However, GPS has inadequate accuracy due to the signal blockage by buildings and multipath effect. Besides GPS, RADAR and LIDAR can achieve quite high accuracy, but [..]

Scanning Probe Microscopy

Scanning probe microscopy (SPM) has revolutionized the fields of materials, nano-science, chemistry, and biology, by enabling mapping of surface properties and surface manipulation with atomic precision. However, these achievements require constant human supervision; fully automated SPM has not been accomplished yet. Researchers demonstrate an artificial intelligence framework based on machine learning for autonomous SPM operation [..]

Organ-On-A-Chip

MIT biological engineers have created a multitissue model that lets them study the relationships between different organs and the immune system, on a specialized microfluidic platform seeded with human cells. Using this type of model, sometimes called “organ-on-a-chip” or “physiome on-a-chip,” the research team was able to explore the role of circulating immune cells in [..]

Terahertz Waves

Terahertz waves are becoming ever more important in science and technology. They enable us to unravel the properties of future materials, test the quality of automotive paint and screen envelopes. But generating these waves is still a challenge. A team of researchers has now developed a germanium component that generates short terahertz pulses with an [..]
