DOI: 10.1016/j.optlaseng.2021.106569
Abstract: Abstract Since the ptychographic encoding can transform the secret information into series of diffractive patterns optically, it achieves the high security for information hiding. However, traditional ptychographic encoding requires the mechanical movements of the illuminated… read more here.
