    摘要： Disclosed is a functional NIRS imaging system including an elastomeric cap, a set of transmit optical fibers and a set of receive optical fibers terminating on the inside surface of the elastomeric cap. A pair of light sources combines to produce a collimated light beam at two wavelengths. An optical modulation system, converts the light beam into a plurality of probe light beams, modulates the plurality of probe light beams with a set of pseudo-orthogonal codes and directs each probe light beam into a transmit fiber. An optical detection system accepts scattered photons from subcutaneous tissue underneath the elastomeric cap as a plurality of collected light beams and converts them into a time series of electronic images, stores the electronic images into the memory and processes the electronic images using the pseudo-orthogonal codes. The system displays the resulting image on a display as a hemoglobin oxygen saturation map.
