Figure Legend:
The red and blue phosphor intensity, modulated in space (x) around the background intensity R BG and B BG, are shown.
In addition, the sinusoids alternate in time around their space and time average intensity (=background intensity), hence
every half time cycle the contrast reverses. The gratings change in time and space with the same temporal and spatial
frequency. The sum of the striped gratings produces a homochromatic luminance grating that changes in intensity but
not in chromaticity. The two solid gratings are offset from each other by 180° and form the heterochromatic grating.
