Embodiments of the present invention disclose a high-throughput single-molecule magnetic resonance measurement apparatus and measurement method. The laser emitted by the laser generation component in the measurement apparatus is multi-point excitation light, and the phases of the multi-point excitation light are not completely identical. When exciting the nitrogen-vacancy (NV) centers in the diamond sample, this setup can simultaneously excite multiple NV centers located along the optical path of the multi-point excitation light, achieving simultaneous measurement of multiple NV centers in a single run and enhancing measurement efficiency. Besides, the laser spots formed by each excitation point of the apparatus are relatively small. When exciting multiple NV centers in the diamond sample, each excitation point only irradiates a small area, which allows a single NV center to serve as a magnetic resonance sensing unit with high spatial resolution, thereby enabling the measurement of single-molecule signals.
