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 ...

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 ...

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 ...

A survey of optical imaging and spectroscopy for the study of the human brain has reported that the field is currently "only at the beginning of this optical revolution." Published in SPIE ...

Cerebral blood flow measurements: Diffuse correlation spectroscopy (DCS) using superconducting nanowire single-photon detectors (SNSPDs) produced 16 times higher signal-to-noise ratio than DCS using ...

Superconducting detectors are a leading technology for the detection of single photons, but have been limited in the number of pixels that they can offer. A 400,000-pixel superconducting nanowire ...

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 ...

In order to function properly, the brain requires a steady flow of blood through the cerebral arteries and veins, which deliver oxygen and nutrients and also remove metabolic byproducts. Therefore, ...

Near-infrared spectroscopy, known as NIR spectroscopy or NIRS, is a long-established analytical technique. For over 30 years, it has proven to be a fast and reliable method for measuring chemical and ...
