International audienceHolography, invented by Denis Gabor in 1948, allows the recording and reconstruction of a wavefront amplitude and phase. The development of optical holography started, in 1960, with the laser. The holographic principles and the most

Hyperspectral tomographic diffractive microscopy: Development and applications
Abstract Tomographic Diffractive Microscopy (TDM) provides label‐free three‐dimensional imaging of transparent samples with resolution surpassing confocal limits. At IRIMAS, successive instrumental developments since 2009 have enhanced TDM capabilities through transmission, reflection, isotropic, polarisation‐sensitive, and dual‐view configurations ...

In operando imaging of the space‐charge region in a 4H‐SiC MOSCAP using STEM‐EBIC
Abstract In situ biasing electron microscopy is the necessary step forward in being able to characterise nanoscale devices and device interfaces. STEM‐EBIC is a new approach that can help fill the missing gaps in creating reproducible methodologies for in situ biasing TEM.

Optical HAAR Wavelet Transforms using Computer Generated Holography [PDF]
This research introduces an optical implementation of the continuous wavelet transform to filter images. The wavelet transform is modeled as a correlation process and is implemented with a Vander Lugt correlator.

Multitask Diffractive Deep Neural Networks Enabled by Joint Distance–Frequency Encoding
A joint distance–frequency encoding strategy enables a single passive diffractive neural network to switch among four computational tasks. By combining mechanically tunable layer spacing with a dual‐frequency phase‐independent metasurface, the same hardware performs orbital angular momentum classification, direction recognition, logic operations, and ...

The object beam and the reference beam interfere at the camera sensor surface and multi‐angle tomographic recording based on off‐axis digital holography. ABSTRACT Single‐frame fringe pattern analysis in digital holographic interferometry (DHI) is essential for precision phase measurement under dynamic conditions. Recent advances in deep learning within
