Why do photons exist? Classical physics gives a derivation, but can not explain the essence and strange properties of photons. Quantum theory suggests that photons are nonlocal particle and differ significantly from ordinary microscopic particles. However, no theory can provide a concrete image of the photon, which causes difficulties in the definition of a single photon. Photons can be obtained from light pulses, the number of which follows the Poisson distribution, and can also be defined from the light power, the photons is actually a kind of weakest light source.

In this article we propose a Photon chamber to detect the traces of the light beam in the grating experiments, namely to visualize the passage of light beam.The experiments show that the light beam behaves as particles moving through the Photon chamber, while still distributes as waves. Diffraction patternPhoton chamber Four Light tracks Diffraction patternPhoton chamber Multi Light tracksThe Photon chamber is inexpensive and discloses novel phenomena.
