Single-Photon 360° Spin Jitter Range Measurement Study

The motion characteristics of microscopic particles are one of the core contents of basic physics research. As a key microscopic particle, photons have important scientific significance in the measured data of their intrinsic motion states. This paper abandons complex theoretical assumptions and designs a minimal experimental scheme without occlusion or obstacles. By emitting single photons one by one and recording their landing positions on a planar background plate, the 360° spin jitter range of single photons is directly measured. The experiment is simple to operate and logically intuitive, which can obtain the real motion parameters of photons, provide an objective measurement basis for the study of microscopic particle motion laws, and fill the gap in relevant basic measured data.
