Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...

Neurophotonics has published the second part of a comprehensive two-part series that provides an extensive toolkit of optics and photonics technologies for exploring brain health and function. The ...

Monitoring the flow of blood to the brain can reveal much about how it works. An increase in blood flow usually accompanies neuronal activity, whereas a decrease in the flow can be indicative of ...

Diffuse optical techniques have proven to be valuable methods for non-invasively observing blood flow in living subjects. A number of modalities have been developed, with diffuse correlation ...

Diffuse correlation spectroscopy (DCS) is used for noninvasive detection of blood flow. However, current DCS devices need to be improved to increase the signal-to-noise ratio for more accurate ...

As the Apple Watch’s ECG-reading tech has made clear, wearable devices have moved well beyond high-tech gimmicks and become genuine lifesavers. The latest demonstration of this is a new device, ...

In the field of clinical instrumentation and life science research, sensing and optical spectroscopy perform vital roles in a range of applications. Optical spectroscopy offers an optimal method for ...

An increase in intracranial pressure (ICP) is a dangerous condition that can be caused by brain bleeds, a brain tumor, cerebral edema, traumatic brain injury, and hydrocephalus. ICP monitoring is thus ...

The Drexel Ultrasound and Optics Wound Healing Team was formed as a collaboration between the ultrasound work of Dr. Peter A. Lewin and the optics team of Drs. Michael S. Weingarten and Leonid Zubkov ...

“Optical imaging and spectroscopy for the study of the human brain” is the second of two field status reports to be published by Neurophotonics this year BELLINGHAM, Washington, USA — The SPIE journal ...
