Safety assessment of near infrared light emitting diodes for diffuse op-tical measurements
ABSTRACT
Near infrared (NIR) light has been used widely to monitor important hemo-
dynamic parameters in tissue non-invasively. Pulse oximetry, near infrared spec-
troscopy, and diffuse optical tomography are examples of such NIR light-based
applications. These and other similar applications employ either lasers or light
emitting diodes (LED) as the source of the NIR light.
