We fabricate translucent metasurfaces that generate completely independent images in transmission for the opposite directions of illumination at the third-harmonic frequency.The authors thank V. Asadchy and A. Poddubny for fruitful discussions, D. Smirnova for her generous help and suggestions, and also acknowledge a help from F. Tjiptoharsono with the fabrication etching recipe. S.
