UNC School of Medicine researchers, led by Ian Shih, Ph.D., associate professor of Neurology and Biomedical Research Imaging Center, developed an improved fiber-based optical method to measure ...

Particle Image Velocimetry (PIV) and optical flow methods represent two cornerstone approaches in experimental fluid dynamics and motion estimation. PIV employs tracer particles seeded in a fluid, ...

Researchers at Korea University, Seoul, have developed a new all-optical method for driving multiple highly dense nanolaser arrays. The approach could enable chip-based optical communication links ...

Recent advances in optical imaging and sensing have significantly improved our ability to investigate biological and material systems. However, many ...

Dark matter is a mysterious type of matter that does not emit, absorb, or reflect light, yet is predicted to account for most of the universe's mass. While physicists have gathered extensive indirect ...

Central nervous system (CNS) diseases such as Alzheimer's disease (AD) manifest early at the microscopic (i.e. cellular) level, deep in the brain. Yet, optical microscopes that can see cells in the ...

Transferring optical information in free space with large bandwidth and high transmission capacity has gained significant attention in various applications, such as remote sensing, underwater ...

Anritsu Corporation has developed the industry’s first Multi-Channel Fibre Tester MT9100A, enabling transmission quality evaluation of multicore fibres supporting next-generation high-capacity optical ...

Want to call someone a quick-thinker? The easiest cliché for doing so is calling her a computer – in fact, “computers” was the literal job title of the “Hidden Figures” mathematicians who drove the ...

Irregularities on a surface determine how rough it is. Surface roughness can be evaluated by visual appearances and tactile sensation and can be measured using a numerical scale. A surface condition ...
