It is shown that the bilinear representation of the Lorentz group is the natural language for the polarization of light. The combined effect of attenuation and phase-shift filters leads to a two-by-two representation of the Lorentz group, which can then be translated into the bilinear representation. The coherency matrix is a representation of the six-parameter Lorentz group.
Within the wavelet framework, it is shown that it is possible to construct a Lorentz-covariant superposition of light waves. The concept of window allows the definition of a finite difference between wavelets and photons. It is pointed out that a windowed function is as accurate as any continuous function which may be constructed from a discrete set of experimental data.
