On the Cover: Review of Fresnel incoherent correlation holography with linear and non-linear correlations [Invited]
The image on the cover of Chinese Optics Letters Volume 19, Issue 2, indicates that Fresnel incoherent correlation holography (FINCH) is a well-established incoherent imaging technique. In FINCH, three self-interference holograms are recorded with calculated phase differences between the two interfering, differently modulated object waves and projected into a complex hologram.

On the Cover: Wavefront-selective Fano resonant metasurfaces
The image on the cover of Advanced Photonics Volume 3, Issue 2, contains three identical metasurfaces, each illuminated by a localized source producing a diverging vortex beam originating at a different distance. The metasurface in the foreground shows reflection of a single color (orange), indicating that the surface interacts only with this wavelength and specific wavefront. Provided by A. Overvig and A. Alù, researchers from City University of New York, the image is based on the research presented in their article "Wavefront-selective Fano resonant metasurfaces", Adv. Photon. 3(2) 026002, doi 10.1117/1.AP.3.2.026002.
