Experimental Research on the Measured Range of Single-Photon Spin Jitter (V2)

The kinematic properties of microscopic particles represent a core research direction in fundamental physics, yet standardized comparative measured data for the spatial jitter range of photons remain scarce. This paper establishes two types of polarization optical paths combined with two light source modes, forming four groups of comparative experiments: single-stage two polarizers with continuous light source, single-stage two polarizers with single-photon emission, two-stage four polarizers with continuous light source, and two-stage four polarizers with single-photon emission. The single-stage polarizers can be adjusted to a mutually perpendicular state to realize extreme angle screening. The experiment adopts an unobstructed free-flight optical path and records photon landing points via a planar receiving plate. Tests cover full-band photons including microwaves, infrared light, visible light, ultraviolet light and X-rays to compare spot size differences under various experimental conditions. The four groups of experiments constitute a cross-comparison system capable of distinguishing the multi-photon superposition diffusion effect from the intrinsic jitter range of single photons, as well as comparing the measurement accuracy of single-stage and two-stage polarization screening. Quantitative data on the photon jitter range can be obtained to fill gaps in relevant measured data and provide complete experimental support for the mechanism of polarization action and microscopic optical theories.
