Simultaneous imaging of multiple objects of different data classes using a diffractive camera. a Schematic and the blind testing results of a three-layer diffractive camera and a five-layer diffractive camera. The output images in each row were normalized using the same constant for visualization. b Phase modulation patterns of the converged diffractive layers for the three-layer diffractive camera design. c Phase modulation patterns of the converged diffractive layers for the five-layer diffractive camera design
