Optical methods have been used to measure physiological variables for decades, as is
apparent from other chapters in this book. However, the use of diffuse optical light for …

Brain activity is associated with changes in optical properties of brain tissue. Optical
measurements during brain activation can assess haemoglobin oxygenation, cytochrome-c …

In this chapter, we review the use of noninvasive optical imaging methods in studying
human brain function, with a view toward their possible applications to neuroergonomics …

This review describes the unique opportunities and challenges for noninvasive optical
mapping of human brain function. Diffuse optical methods offer safe, portable, and radiation …

A new set of techniques allows for the study of brain function by near‐infrared light,
exploiting two optical phenomena: Changes in light absorption are determined by changes …

Since the initial demonstration of near-infrared spectroscopy (NIRS) for noninvasive
measurements of brain perfusion and metabolism in the 1970s, and its application to …

Optical brain imaging has seen 30 years of intense development, and has grown into a rich
and diverse field. In-vivo imaging using light provides unprecedented sensitivity to functional …

Diffuse optical imaging is a medical imaging technique that is beginning to move from the
laboratory to the hospital. It is a natural extension of near-infrared spectroscopy (NIRS) …

Time-resolved near-infrared spectroscopy is an optical technique which can be applied in
tissue oxygenation assessment. In the last decade this method is extensively tested as a …

Near-infrared (IR) light easily penetrates biological tissue, and the information offered by in
vivo spectroscopy of cerebral oxygenation is detailed and comes with a high temporal …
