Yes, FFT is an algorithm, a computer-optimized implementation of the Fourier transform.
Speaking of optics, the famous slit-experiment, where you can see the diffraction patterns of light passing through one or more slits, is the fraunhoffer-pattern, the 2D fourier transform of the slit: http://physics.stackexchange.com/questions/94852/why-is-the-...
