Three dimensional imaging of short pulses [PDF]
Optics Communications, 2004 We exploit a slightly noncollinear second-harmonic cross-correlation scheme to map the 3D space-time intensity distribution of an unknown complex-shaped ultrashort optical pulse. We show the capability of the technique to reconstruct both the amplitude and the phase of the field through the coherence of the nonlinear interaction down to a resolution of

FRET Imaging in Three-dimensional Hydrogels [PDF]
Journal of Visualized Experiments, 2016 Imaging of Förster resonance energy transfer (FRET) is a powerful tool for examining cell biology in real-time. Studies utilizing FRET commonly employ two-dimensional (2D) culture, which does not mimic the three-dimensional (3D) cellular microenvironment.

Invertible Mosaic Image Hiding Network for Very Large Capacity Image Steganography [PDF]
arXiv, 2023 The existing image steganography methods either sequentially conceal secret images or conceal a concatenation of multiple images. In such ways, the interference of information among multiple images will become increasingly severe when the number of secret images becomes larger, thus restrict the development of very large capacity image steganography ...

An Arduino-based, low-cost imaging incubator for extended live cell imaging [PDF]
, 2022 In order to image live cells for prolonged periods of time, an Arduino-based, low-cost imaging incubator was constructed. The imaging incubator keeps cells viable by controlling for temperature and CO2 in order to maintain physiological conditions for cells during imaging.

Three-dimensional imaging for large LArTPCs [PDF]
Journal of Instrumentation, 2017 High-performance event reconstruction is critical for current and future massive liquid argon time projection chambers (LArTPCs) to realize their full scientific potential. LArTPCs with readout using wire planes provide a limited number of 2D projections.
