Open-Set Learning-Based Hologram Verification System Using Generative Adversarial Networks
IEEE Access, 2022 In this study, we address the hologram authenticity challenge by introducing a novel deep-learning based end-to-end hologram verification system. The system ultimately makes the decision whether the hologram image captured from a mobile application is ...

When the image takes over the real: Holography and its potential within acts of visual documentation [PDF]
, 2020 In Camera Lucida, Roland Barthes discusses the capacity of the photographic image to represent “flat death”. Documentation of an event, happening, or time is traditionally reliant on the photographic to determine its ephemeral existence and to secure its

Pseudo-nondiffracting beams generated by radial harmonic functions [PDF]
, 1995 A Fourier hologram with the distribution of a radial harmonic function creates a nondiverging beam in the far field. The properties of this beam are analyzed and the beam is demonstrated. We also give a set of theorems that describe the relations between
