Fig. 3: Sample input-output images for the ground truth transformation presented in Fig. 1b and the optical outputs by the diffractive designs for two different choices of N (N = 482 and N = 802).

Fig. 3

The magnitude and phase of the normalized output fields and the differences of these quantities with respect to the ground truth are shown. \(\left| {\angle {{{\boldsymbol{o}}}} - \angle \widehat {{{\boldsymbol{o}}}}^\prime } \right|_\pi\) indicates wrapped phase difference between the ground truth and the normalized output field
