The in vivo optical properties of a piglet brain were measured using a time
-resolved system at three different wavelengths (759, 794, 824 nm). To sepa
rate the contribution of different head layers to the detected signals, the
measurements were acquired from the surfaces of shin, skull, dura mater an
d brain. The source-detector distance was chosen to assure a mean penetrati
on depth within each layer. Measurements were analyzed and compared with th
e results of other in vivo measurements reported in literature.
