Synthesized femtosecond laser pulse source for two-wavelength contouring with simultaneously recorded digital holograms

open access: yesOptics Express, 2009
A dual-wavelength femtosecond laser pulse source and its application for digital holographic single-shot contouring are presented. The synthesized laser source combines sub-picosecond time scales with a wide reconstruction range. A center wavelength distance of the two separated pulses of only 15 nm with a high contrast was demonstrated by spectral ...

A personal 360° view of applications of ‘biomimetic’ molecular recognition

open access: yesJournal of Chemical Technology &Biotechnology, Volume 101, Issue 7, Page 1300-1311, July 2026.
Abstract Molecular recognition between biological molecules has formed the basis for innumerable applications in biotechnology for the last seven decades or so. Techniques such as affinity chromatography, solid‐phase and aqueous two‐phase extraction, affinity precipitation, biomimetic catalytic systems, biosensors and molecular imprinting all exploit ...

Combining the Underwater Vision Profiler 6 with sediment traps to measure in situ velocity of marine particles

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 7, July 2026.
Abstract Particles sinking from the surface to the deep ocean play a key role in the biological carbon pump, whose efficiency depends partly on sinking velocities. Over the last decade, in situ imaging has enabled critical advances in our understanding of particle dynamics in the ocean.

Holographic antennas realized from interference patterns determined in the presence of the dielectric substrate

open access: yes, 2006
Holographic antennas are attractive due to their low-profile and potentially high gain. These antennas are synthesized from the interference pattern of a reference wave and a plane wave.

Object reconstruction from in-line Fresnel holograms without explicit depth focusing

open access: yes, 2004
We propose two computational techniques for extracting object cross-sectional shape information from digitized in-line Fresnel holograms that do not require prior knowledge of object depths but recover relative depth information along the way.

APPLICATION OF A SLM SOFTWARE FOR A COMPUTER-SYNTHESIZED HOLOGRAM

open access: yes, 2020
We consider a method of using software for a spatial light modulator (SLM), using the method of computer- synthesis of holograms to generate an input image into a holographic interference picture and output to a holographic projection system that ...
