Digital holographic interferometry for particle detector diagnostic
2022 45th Jubilee International Convention on Information, Communication and Electronic Technology (MIPRO), 2022 In high precision scattering experiments particle tracks must often be reconstructed from a series of hits in successive detector planes. The relative distance between these planes is a critical parameter that must be monitored during operation. To address this problem we have developed a digital holographic interferometer dubbed Holographic Alignment ...

Noise and aliases in off-axis and phase-shifting holography [PDF]
, 2008 We have compared the respective efficiencies of off-axis and phase-shifting holography in terms of noise and aliases removal. The comparison is made by analyzing holograms of an USAF target backlit with laser illumination, recorded with a charge-coupled ...

Harmonically matched grating-based full-field quantitative high-resolution phase microscope for observing dynamics of transparent biological samples [PDF]
, 2007 We have developed a full-field high resolution quantitative phase imaging technique for observing dynamics of transparent biological samples. By using a harmonically matched diffraction grating pair (600 and 1200 lines/mm), we were able to obtain non ...

Short-time Fourier transform laser Doppler holography [PDF]
, 2013 We report a demonstration of laser Doppler holography at a sustained acquisition rate of 250 Hz on a 1 Megapixel complementary metal-oxide-semiconductor (CMOS) sensor array and image display at 10 Hz frame rate.

Digital Holography at Shot Noise Level [PDF]
, 2010 By a proper arrangement of a digital holography setup, that combines off-axis geometry with phase-shifting recording conditions, it is possible to reach the theoretical shot noise limit, in real-time experiments.We studied this limit, and we show that it

Natural Crystal Structure for Generating Raman‐Like Orbital Angular Momentum States
Advanced Science, EarlyView.This work proposes a strategy for symmetry breaking of the degenerate OAM states relying on the natural anisotropy of crystal gain, to select the handedness of the spatial spiral phase front and further tunable Raman‐like OAM states by thermal‐driven, which clarifies the contribution of intrinsic crystal property to the OAM states and opens a new route

Multiple Reflections on Huygens' Principle
Geophysical Prospecting, EarlyView.ABSTRACT According to Huygens' principle, all points on a wave front act as secondary sources emitting spherical waves and the envelope of these spherical waves forms a new wave front. In the mathematical formulation of Huygens' principle, the waves emitted by the secondary sources are represented by Green's functions.
