Fig. 3: All-optical linear transformations of test intensity patterns under spatially incoherent illumination performed by diffractive networks trained using the indirect approach.
From: Universal linear intensity transformations using spatially incoherent diffractive processors
All-optical linear transformation of structured intensity patterns such as letters U, C, L, and A by the same diffractive networks as in Fig. 2, accompanied by the patterns resulting from the numerical inverse mapping of the all-optical outputs through multiplication by A−1
