Left: simulated focal plane of the phase pattern. Right: phase and aperture. On the focal plane several PSF’s can be seen. Theleft and right PSFs are the PSFs that contain the phase pattern. The top and bottom correspond to the light that scattersaway due to the grating mask. And in the center there is a 1 percent leakage term. The horizontal PSFs are at ± 10λ∕D and the aperture PSFs are at ±50λ∕D
