Lossless Compression Using the Ramanujan Sums: Application to Hologram Compression
IEEE Access, 2020 The Ramanujan sum, introduced by S. Ramanujan, has been utilized-among other applications-for signal processing. It has recently been suggested that transforms using the Ramanujan sums may also provide the benefit of data compression. This study presents

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

Waveguide holograms: A new approach to hologram integration
Optics Communications, 1976 Abstract A new class of holography is proposed, in which (1) the evanescent part of a guided wave, or (2) the guided wave in a thin-film hologram is utilized as the reference wave and/or the illuminating one. The hologram was designated as “wave-guide hologram” and has advantages in the possibility of integration, wide field of view, and compactness ...

A new objective quality metric for phase hologram processing
ETRI Journal, 2021 Because of its convenience and compatibility with various image processing techniques, digital image representation of holograms is generally used in digital holography, and thus, quality assessment of digital holograms is an essential issue.

Nature CommunicationsSpatiotemporal structured light has opened up new avenues for optics and photonics. Current spatiotemporal manipulation of light mostly relies on phase-only devices such as liquid crystal spatial light modulator to generate spatiotemporal optical fields with unique photonic properties.

Multimodal Mixed Reality Impact on a Hand Guiding Task with a Holographic Cobot
Multimodal Technologies and Interaction, 2020 In the context of industrial production, a worker that wants to program a robot using the hand-guidance technique needs that the robot is available to be programmed and not in operation.
