Abstract
An optical pumping-based multimodal fusion detection apparatus is provided, relating to the field of brain-computer interfaces. The system includes a laser generation module, laser path control module, atomic vapor cell, photodetection module, ultrasonic detection module, and data processing module. The photodetection module, ultrasonic detection module, and data processing module function as a detection module. The detection module collects the laser intensity and polarization variation signals of the first laser after passing through the atomic vapor cell to output local magnetic field variations in the brain caused by neural discharges. It also collects ultrasonic signals corresponding to an interaction of the second pulsed laser with the measured part to output the subject's blood oxygen signal.
