Polarimetric imaging, which considers the polarization of light in every pixel of an image, can provide a fuller view of an object than traditional cameras. Polarized light, made of electromagnetic waves, travels along a single plane or on a rotating plane. This technology can reveal information the human eye may miss, such as pointing out [..]

By examining exhaled air, researchers have created a non-invasive breath analyzer method to monitor the development of tiny blood clots called immunothrombosis. Due to inflammation, immunothrombosis can lead to serious consequences in individuals with severe COVID-19 and exacerbate sepsis, heart disease, diabetes, and other illnesses. The researchers created a non-invasive breath analyzer method that uses [..]

Researchers have created an optomechanical platform for superconducting circuits exhibiting high-fidelity quantum control and ultra-low quantum decoherence, the longest quantum state lifetime in a mechanical oscillator ever obtained results from their ground-breaking work with a “vacuum-gap drumhead capacitor,” opening up new possibilities in quantum computing and sensing. The challenge for optomechanical systems operating in the quantum [..]

Although chemotherapy is a highly effective cancer treatment, some cancer cells become resistant to it through a dormant phase known as senescence. These therapy-induced senescent (TIS) cells can develop resistance to treatment, even become aggressive, and spread. Early TIS cell detection may be essential to stopping their spread; however, the screening techniques must be more [..]

Researchers have created a wearable optical device to detect bleeding during or after delivery early. This severe, profuse bleeding, responsible for about 30% of maternal fatalities worldwide, can be difficult to identify before it becomes an emergency. According to studies, the greatest strategy to avoid mortality from postpartum hemorrhage is to diagnose and treat the [..]

Scientists create computer models of the patient’s eyes to choose the best intraocular lenses and visual simulators for patients to experience what they would see with them. Researchers built computational eye models using the corneas of patients who had undergone LASIK surgery to understand better how conventional intraocular lenses and lenses intended to improve depth [..]

Researchers’ new technique, which enhances conventional machine vision and perception, is improving the field of robotics and autonomy. They have created heat-assisted detection and ranging, or HADAR. Conventional active sensors that gather three-dimensional data, such as LiDAR, radar, and sonar, have disadvantages such as interference and potential eye safety hazards. Conventional thermal imaging is a [..]

When added to silicate glass, niobium oxide (Nb2O5) causes silica network polymerization, raising bond density and connectivity and improving specialty glass’s mechanical and thermal durability. It is the first study to demonstrate this effect. The work integrated computational modeling with actual Raman and nuclear magnetic resonance spectroscopy findings. In addition to the previously reported findings, [..]

When it comes to high-capacity screening tests, or assays, for detecting and targeting certain cells or analytes (substances whose chemical makeup is the goal of identification), the static droplet array (SDA) is an essential and fundamental instrument. One significant technological barrier that prevents the SDA’s wider use is the extraction and collection of target droplets [..]

Virtually applying makeup before completing a purchase or having pterodactyls swoop above in a game are just two examples of how augmented reality and other immersive technologies are changing how we play, watch, and learn. Immersion displays would realize their full potential using low-cost, ultra-small light-emitting diodes (LEDs) or micro-LEDs. However, these LEDs still need [..]

The rapid expansion of artificial intelligence (AI) and machine learning (ML) applications requires effective connectivity between processing units and high-speed transmission. It has increased interest in optical interconnects, especially for short-range connections between XPUs (CPUs, GPUs, and memory). When compared to conventional methods, silicon photonics is showing promise as a technology for enhanced performance, cost-effectiveness, and [..]

Transmission electron microscopes use inline holography to measure and rectify images in real space and to measure magnetic and electric fields. On the other hand, it needs help with incoherent dispersion and low-spatial-frequency information transmission. This work optimizes reconstruction parameters and compares the outcomes using gradient flipping, phase prediction, and incoherent background removal. Transmission electron [..]

To enhance medical imaging, a group of researchers has created a novel method called quantitative photoacoustic tomography, or QPAT. QPAT is an imaging modality that combines optical tomography with ultrasonography, an imaging method that employs sound waves to view characteristics inside the body. It uses data on the strength of acoustic waves as detected on [..]

Artificial materials that are skilled at influencing perception are called metasurfaces. Metasurfaces are attracting much interest as optical components that enable the miniaturization of optical systems for the next generation of virtual and augmented reality and LiDAR. They enable lenses to be shrunk to one 10,000th the size of normal lenses. Countries may gain a considerable [..]

Researchers have demonstrated that chip-based optical frequency combs with sufficient output power for optical atomic clocks and other practical applications may be made using dissipative Kerr solitons (DKSs). The development could result in equipment built on chips that can do precise tests previously only achievable in a few specialist labs. In metrology, frequency combs are [..]

Two entangled light particles were seen in real-time by scientists using a first-of-its-kind method, giving rise to the striking quantum “yin-yang” sign. Future quantum experiments might be greatly accelerated by the new technique known as biphoton digital holography, which makes use of an ultra-high-precision camera. Two photons can become irrevocably linked by a relationship called [..]

Using a cascaded architecture of gas-filled hollow-core fiber (HCF), bare lithium niobate (LN) crystal plate, and a specially designed chirped periodically poled lithium niobate crystal (CPPLN), researchers have demonstrated four-octave-spanning intense ultraviolet-visible-infrared (UV-Vis-IR) full-spectrum laser source with the energy of 0.54 mJ per pulse. The HCF-LN system can produce an intense one-octave bandwidth mid-IR laser [..]

According to a new study, artificial intelligence can forecast the on- and off-target behavior of CRISPR tools that target RNA rather than DNA.
