Modern Stroke Diagnosis As discussed in a recent article, strokes are one of the most common causes of death in the world. One study found that about 90% of all strokes occur due to cerebral ischemia while ...

  An Introduction to Nanophotonics: Something Big from Something Small In recent years there has been a lot of work with nanophotonics in optical physics and engineering. This is a part of the rising ...

Introduction to Elastography Elastography is a type of imaging modality that provides information on the elastic properties and stiffness of the tissue being reviewed based on spatial distribution. It is ...

Photoelectronic devices combine the vast use of electronics for processing information with the detection and the manipulation of light. Devices such as photodiodes are useful for detecting incoming light ...

Nitrogen vacancy centers in diamond are an exciting platform to build very accurate sensors. These vacancy centers provide very precise energy levels that can be influenced and controlled by various ...

Introduction to Presbyopia As we grow older the lens of the eye becomes much more rigid, hindering the ability to properly focus light onto the retina. This condition, presbyopia, affects approximately two ...

Quantum dots, sometimes referred to as semiconductor nanocrystals, are an exciting emerging technology that we have covered previously on our blog. Quantum dots are artificial nanoparticles (on the order ...

Optical fibers are a convenient instrument for robust light transfer. Their low losses have enabled their wide use in long distance telecommunication systems while service providers like AT&T, Verizon ...

In 1842, Johann Doppler delivered his paper on Doppler effect to Royal Bohemian Society. In his paper “On the Colored Light of Double Stars and Some Other Heavenly Bodies”, he arrived at the ...

Beam profiling systems are an essential technology to ensure the quality and uniformity of lasers. Beam profilers measure the optical spatial intensity of an input laser beam,  providing information about ...
