I have a diffraction grating through which I shined a 532 nm laser. A detector which can pan 360˚ was rotated around and picked up all of the transmitted diffraction peaks. Shown in the graph graph attached are the intensities of the peaks against the angle. My question is, is it possible to treat these peaks as Fourier frequency components and then rebuild what would be the "time" domain from them, or in this case an image of the pattern of the diffraction grating? If more info is required, or this would be better moved to another section, please let me know.
