Is this using Fourier transforms to describe light while it's in a wave form?

I understood some of the words

yes Fourier transform is a function derived from a given function and representing it by a series of sinusoidal functions.

 

Its handy on any waveform

Doesn't that mean we could accurately reconstruct wave phenomena in an animation? Why can't I ever find something like this?

It would certainly help program wavefunctions in an animation. Ss well as reconstruct it. As far as finding something like this. Its in your more advanced math textbooks. Its also part of the curriculum for electronics. Numerous electronic books will go into some detail of Fourier transforms. Though you will also find something similar

 

Laplace transforms.

Little hint ( although QM and relativity seems complicated. That complication usually stems from the unfamiliarity in its terminology)

 

Yet that terminology stems from everyday mathematics.

The Laplace transform doesn't seem to get a quantum speedup, despite being similar to the Fourier transform (which does), because the Laplace transform doesn't preserve lengths.

I'm looking into Q talbot carpet, that might be close to what I'm after.
