Fresnel Diffraction Using a He-Ne Gas Laser
Moen, Allen L.; Vander Meulen, David L.
Amer J Phys, 38, 9, 1095-1097, Sep '70
Describes an advanced laboratory experiment of Fresnel diffraction which uses a He-Ne gas laser as the source and a wire as the opaque diffracting strip. A photograph of the diffraction pattern is compared with the intensity diagram predicted by the Cornu spiral method. Agreement is clear and impressive, although minor differences are detectable.
