Abstract: A multimodal fusion detection apparatus and method based on optical pumping and photoacoustic imaging are provided, relating to the field of fusion detection technology. In the apparatus, the atomic vapor cell detection path and the first laser irradiation path are both directed toward a target region and at least partially overlap. In this way, the detection paths of optical pumping and photoacoustic imaging are at least partially coincident, ensuring that electrophysiological signals and blood oxygen signals originate from the same tissue region and avoiding the spacing constraints of conventional sensors. Thus, the detection path of the atomic vapor cell can be used for both magnetic field detection and photoacoustic detection, enabling simultaneous acquisition of magnetic and photoacoustic signals at a single detection point, achieving hardware reuse for multimodal fusion detection at the same location and time, reducing device size, and minimizing crosstalk among multimodal sensors.
