自己診断のための近赤外分光画像計測プローブの開発

We develop a multi-channel probe system and a scanning probe system for a near-infrared spectroscopy imaging.
The multi-channel probe system is composed of one light source module and eight photodetector modules. To obtain
a photon path from the light source to the detector using the multi-channel probe system, we utilize a phantom
containing a movable absorber in a liquid light scattering medium. The scanning probe system is composed of a nearinfrared
light source, a detector, and a light source indicating a position. The probe position is detected by a camera.
We realize an isotropic spatial response by use of an improved probe containing two source-and-detector pairs in a
cross arrangement.
