High-speed imaging in fluids [PDF]
Experiments in Fluids, 2013 High-speed imaging is in popular demand for a broad range of experiments in fluids. It allows for a detailed visualization of the event under study by acquiring a series of image frames captured at high temporal and spatial resolution. This review covers high-speed imaging basics, by defining criteria for high-speed imaging experiments in fluids and to

Compressive high-speed stereo imaging
Optics Express, 2017 A compressive high-speed stereo imaging system is reported. The system is capable of reconstructing 3D videos at a frame rate 10 times higher than the sampling rate of the imaging sensors. An asymmetric configuration of stereo imaging system has been implemented by including a high-speed spatial modulator in one of the binocular views, and leaving the ...

Compressive Coded Rotating Mirror Camera for High-Speed Imaging
Photonics, 2021 We develop a novel compressive coded rotating mirror (CCRM) camera to capture events at high frame rates in passive mode with a compact instrument design at a fraction of the cost compared to other high-speed imaging cameras. Operation of the CCRM camera

Spaceborne ISAL Imaging Algorithm for High-Speed Moving Targets
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 During the spaceborne inverse synthetic aperture ladar (ISAL) imaging, the radial velocity between the piggyback satellite of ladar and the observed satellite is usually relatively large, which will introduce the inner-pulse Doppler that cannot be ...

A high-speed gateable image pipeline [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1996 Abstract We present the performance of a high-speed gateable vacuum image pipeline, which permits individual images to be delayed and selected from continuous non-repetitive image stream. This device is composed of a vacuum tube equipped with a photocathode at one end, a phosphor screen at the other end, and a system of metal grids in between ...

Ultra high speed imaging of elasticity [PDF]
2002 IEEE Ultrasonics Symposium, 2002. Proceedings., 2003 Ultrafast ultrasonic imaging seems to have a strong potential for medical imaging applications. During the past five years, it has been applied successfully to quantitative assessment of soft tissues elasticity. An ultrafast ultrasonic scanner was built in our lab for quantitatively mapping the shear elasticity of soft tissues.

High-Speed Two-Photon Imaging [PDF]
Cold Spring Harbor Protocols, 2013 The small size of neuronal dendrites and spines combined with the high speed of neurophysiological signals, such as transients in membrane potential or ion concentration, necessitates that any functional study of these structures uses recording methods with both high spatial and high temporal resolutions.
