High-Speed Two-Photon Imaging [PDF]

open access: yesCold 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.

Spaceborne ISAL Imaging Algorithm for High-Speed Moving Targets

open access: yesIEEE 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 ...

High-speed scanless entire bandwidth mid-infrared chemical imaging

open access: yesNature Communications, 2023
Mid-infrared spectroscopy probes molecular vibrations to identify chemical species and functional groups. Therefore, mid-infrared hyperspectral imaging is one of the most powerful and promising candidates for chemical imaging using optical methods.

Freehand scanning photoacoustic microscopy with simultaneous localization and mapping

open access: yesPhotoacoustics, 2022
Optical-resolution photoacoustic microscopy offers high-resolution, label-free hemodynamic and functional imaging to many biomedical applications. However, long-standing technical barriers, such as limited field of view, bulky scanning probes, and slow ...

Signal Conditioning in Process of High Speed Imaging

open access: yesAdvances in Electrical and Electronic Engineering, 2015
The accuracy of cinematic analysis with camera system depends on frame rate of used camera. Specific case of cinematic analysis is in medical research focusing on microscopic objects moving with high frequencies (cilia of respiratory epithelium).

High speed partial Stokes imaging using a ferroelectric liquid crystal modulator [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2008
This paper describes the implementation of an imaging polarimeter using a single ferroelectric liquid crystal light modulator. It provides partial imaging Stokes information at 234 Hz, much faster than polarimeters using nematic light modulators.

Quantification of Sub-Pixel Dynamics in High-Speed Neutron Imaging

open access: yesJournal of Imaging, 2022
The high penetration depth of neutrons through many metals and other common materials makes neutron imaging an attractive method for non-destructively probing the internal structure and dynamics of objects or systems that may not be accessible by ...
