Magnetic Steganography Using Wide-Field Diamond Microscopy
Diamond NV-center wide-field microscopy enables magnetic steganography by revealing information hidden from conventional optical imaging. Pixel art, barcodes, and QR codes made from Ni/Au mixtures were reconstructed magnetically; contrast-based ESR imaging worked best, and dual microwave driving reduced imaging time threefold.
