Classical wave optics and traditional quantum polarization theory have long adopted the model of orthogonal vector decomposition to explain the light transmission rule of polarizers. This theory artificially decomposes the vibration form of light into the component parallel to the transmission axis and the component perpendicular to the transmission axis. It holds that the parallel component can pass through the polarizer while the perpendicular component is blocked and absorbed by the polarizer. This system is purely a mathematical fitting method, rather than the real microscopic physical process. Based on the core photon model of the Origin of Light Theory, this paper proposes a fundamental revision. A photon is a pure energy state energy point particle, rather than a material point particle with rest mass. The photon has no physical volume and its body cannot be divided. Although the photon body is a geometric single point, it possesses a fixed transverse oscillation range. The photon performs high speed transverse reciprocating oscillation along its fixed inclined axis, forming a stable vibration interval structure. Whether a photon can penetrate the polarizer does not depend on whether the overall vibration inclination of the photon is consistent with the transmission axis. It only depends on the instantaneous position of the photon when it arrives at the polarizer while propagating at the speed of light. For any photon with an inclined angle, as long as it oscillates to the transmission interval of the polarizer at the moment of arrival, the complete energy point particle can transmit directly. After transmission, the original vibration inclination and the full oscillation range of the photon are completely retained. The perpendicular oscillation component neither disappears nor gets corrected. Malus law is only the macroscopic statistical result of the collective motion of massive photons. It is a fitting law of mathematical average value and cannot describe the microscopic light transmission mechanism of a single photon. This paper thoroughly overturns the century old physical interpretation of vector decomposition in polarization, clarifies that mathematical vector splitting is not equivalent to the real physical behavior of particles, fills the core underlying theoretical loophole in the field of optical polarization, and once again refutes the wave foundation of wave particle duality from the microscopic particle level.
