DL-HPM reconstruction results using different input channels. The performance of DL-HPM in general degraded when reducing the input channel to amplitude only or phase only information. Color bar for retardance, from black to white, represents 0 to 1 Rad. Color bar for orientation, from black to white, represents −π/2 to π/2. Color bar for pseudo colored crystals, from left to top to right, represents π, π/2, 0 Rad in the orientation channel. Retardance is represented by the distance from the center of the color bar, ranging from 0 to 0.4. The circled crystals for the amplitude only network show that the network is capable of reconstructing the crystal features in the correct location, but the color is inaccurate due to the errors in the orientation channel. The circled crystals for the phase-only network are either entirely missing or have a retardance that is too low, rejected by the pseudo coloring scheme.
