Grady and I have been working on a script that takes in a large set of pictures of a sheet of holographic glitter, where a picture is taken at every location of a small white box moving along a monitor across from the glitter sheet. The graph we created shows the color of a single glitter pixel when the white box is at that location on the monitor. From this data, I combined the graph with the script I wrote a few weeks ago and created a graph that shows the same thing, just displaying the closest monochromatic wavelength to the RGB value shown and recording that value.
Any photo where the pixel we selected was not lit was not used for this process, as well as any photo where the pixel was fully saturated, or not saturated to at least 15%.
We plan to use these lines to compute a various set of angles that we need, along with the wavelength, to determine the groove spacing of the diffraction grating on our specific holographic glitter sheet.
