Laboratory measurement: Coronagraphic images recorded at different wavelengths (central wavelength in the bottom left and spectral bandwidth in the bottom right of each image). Speckles are minimized using the laser diode at 783 nm. The image size is 12 λ/D × 12 λ/D at 704.5 nm. The color bar gives the intensity normalized by the maximum of the noncoronagraphic image.
