An apparatus and method for the multi-channel functional imaging of the brain. The method comprises: according to an instruction of a central processing unit, choosing to connect to one or more transmitting antennas and receiving antennas (S10); transmitting two light quanta, wherein one is transmitted, via the transmitting antenna, to tissue to be detected, and the other is directly sent to a light quantum receiving module (S20); the light quantum receiving module receiving the light quantum, which is directly transmitted, and another light quantum, which is subjected to reflection, refraction, scattering and a photochemical reaction by the tissue to be detected and the state of which is changed (S30); analyzing and calculating the states of the light quanta to obtain final component data of the tissue to be detected and the thermal activity of and bioelectrical activity data about the tissue to be detected (S40); and according to the activity data, executing the instruction of the central processing unit, and carrying out corresponding image reconstruction (S50). The apparatus has a relatively strong scanning capability, the measurement of data is more direct and more sensitive, the information volume is larger and more stable, and there is no time delay.
