A wearable-type fNIRS brain imaging system, comprising a light source-photoelectric detector module, a control and wireless transmission module, a power source module, and an upper computer; said system is able to solve the problems in a wearable fNIRS brain imaging system or an EEG-fNIRS multi-modal brain imaging system where the relative position of a probe can not be freely adjusted and a detection region is limited; in the present system, the relative positions of a light source probe (1) and a photoelectric detector (2) can be freely adjusted according to actual circumstances, and the distance between the two is automatically measured, which can reduce measurement error of a brain blood-oxygen signal, and allows for flexible adjustment of a cerebral detection region; the system can harmonize with brain electrical signal detection, a brain electricity sensor (7) may be installed at the periphery of the light source probe (1) and a bottom face of a cylindrical casing of the photoelectric detector (2), and distance therebetween synchronously changes with the probe (1), implementing EEG-fNIRS multi-modal brain imaging, and also able to capture brain electrical signals of differing densities.
