Visualization 1 includes four parts. Part I presents the speckle evolution of both monochromatic and polychromatic speckles under the illumination bandwidth ranging from λ = 500 nm to λ = 764 nm. Part II shows the speckle autocorrelation changes with the illumination wavelength and the corresponding PBR function versus illumination spectral width. Part III provides the extended data of Fig. 17. In Part IV, we show a dynamic phase retrieval process of an object ’optics’...
