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 ...

Fluctuation characteristics of the TCV snowflake divertor measured with high speed visible imaging [PDF]

, 2018
Tangentially viewing fast camera footage of the low-field side snowflake minus divertor in TCV is analysed across a four point scan in which the proximity of the two X-points is varied systematically.

Spatio‐Spectral‐Temporal Imaging of Fast Transient Phenomena Using a Random Array of Pinholes

Advanced Photonics Research, 2021
Fast transient phenomena such as light–matter interactions, rapid electrical discharge, light scattering in tissues, and biochemical reactions that generate light signatures can be studied using high‐speed cameras. Herein, a lensless, single camera shot,

Effect of MDI Actuation Timing on Inhalation Dosimetry in a Human Respiratory Tract Model

Pharmaceuticals, 2022
Accurate knowledge of the delivery of locally acting drug products, such as metered-dose inhaler (MDI) formulations, to large and small airways is essential to develop reliable in vitro/in vivo correlations (IVIVCs). However, challenges exist in modeling

High-speed fluorescence image–enabled cell sorting

Science, 2022
Fast and selective isolation of single cells with unique spatial and morphological traits remains a technical challenge. Here, we address this by establishing high-speed image-enabled cell sorting (ICS), which records multicolor fluorescence images and sorts cells based on measurements from image data at speeds up to 15,000 events per second.

Laser beam powder bed fusion of Inconel 718 under high power and scanning speed

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2023
The process map area of laser beam powder bed fusion for the nickel-based superalloy Inconel 718 is investigated using high laser power (600-1000 W) and scanning speeds (1500-3500 mm/s).

Breakup of diminutive Rayleigh jets [PDF]

, 2010
Discharging a liquid from a nozzle at sufficient large velocity leads to a continuous jet that due to capillary forces breaks up into droplets. Here we investigate the formation of microdroplets from the breakup of micron-sized jets with ultra high-speed

High-speed multispectral confocal biomedical imaging [PDF]

Journal of Biomedical Optics, 2014
A new approach for generating high-speed multispectral confocal images has been developed. The central concept is that spectra can be acquired for each pixel in a confocal spatial scan by using a fast spectrometer based on optical fiber delay lines. This approach merges fast spectroscopy with standard spatial scanning to create datacubes in real time ...

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.

Multiple CR Spatiotemporal Compressive Imaging System

Sensors
Higher spatial and temporal resolutions are two important performance parameters in an imaging system. However, due to hardware limitations, the two resolutions are usually mutually restricted.
