Fig. 2

Design schematic and blind testing results of the class-specific diffractive camera. a The physical layout of the three-layer diffractive camera design. b Phase modulation patterns of the converged diffractive layers of the camera. c The blind testing results of the diffractive camera. The output images were normalized using the same constant for visualization
