When multiple light paths combine at a given location on an image sensor, an image mixture is created. Demixing or recovering the original constituent components in such cases is a highly ill—posed problem. A number of elegant solutions have thus been developed in the literature, relying on measurement diversity such as polarization, shift, motion, or ...

Time-Resolved Fluorescent Imaging of Glucose
Journal of Fluorescence, 2004A method for the fluorescent imaging of glucose is described that is based on the detection of enzymatically produced hydrogen peroxide, using the europium(III) tetracycline complex as the fluorescent probe incorporated into a hydrophilic polymer layer.

Femtosecond time-resolved photoelectron imaging
Faraday Discussions, 1999Femtosecond time-resolved photoelectron imaging (FS-PEI) is presented for the first time. This novel method is tested with two-color photoionization of NO via the A 3sσ state and applied to ultrafast dephasing in the intermediate case molecule pyrazine.

Time-resolved Hadamard fluorescence imaging
Applied Optics, 2005We present a new concept for fluorescence lifetime imaging (FLIM) based on time-resolved Hadamard imaging (HI). HI allows image acquisition by use of one single-point detector without requiring a moving scanning stage. Moreover, it reduces the influence of detector noise compared with raster scanning.

Circular Echo-Planar Time-resolved Imaging (cEPTI) for Rapid Time-Resolved and Quantitative Imaging
ISMRM Annual Meeting, 2023EPTI is a highly accelerated time-resolved imaging method for rapid quantitative imaging. To improve the spatiotemporal encoding efficiency of EPTI, we developed a “circular” EPTI sampling trajectory (cEPTI), designed to efficiently traverse a tight circular k-space coverage with full ramp-sampling.

Time-resolved imaging of the reaction coordinate
The Journal of Chemical Physics, 2005Time-resolved photoelectron imaging of negative ions is employed to study the dynamics along the reaction coordinate in the photodissociation of IBr−. The results are discussed in a side-by-side comparison with the dissociation of I2−, examined under similar experimental conditions. The I2− anion, extensively studied in the past, is used as a reference

Photothermal time‐resolved imaging of living cells
Lasers in Surgery and Medicine, 2002AbstractBackground and ObjectivesThermal effects of laser radiation at cell level play very important role in cell functioning and in many laser applications. The aim of this study was to evaluate a new method of photothermal imaging (PTI) for monitoring short‐time nano‐scale thermal effects in individual living cells.Study Design/Materials and ...

Time-Resolved Fluorescence Anisotropy Imaging
2013Fluorescence can be characterized by its intensity, position, wavelength, lifetime, and polarization. The more of these features are acquired in a single measurement, the more can be learned about the sample, i.e., the microenvironment of the fluorescence probe.

FEMTOSECOND TIME-RESOLVED PHOTOELECTRON IMAGING
Annual Review of Physical Chemistry, 2006▪ Abstract Femtosecond time-resolved photoelectron imaging (TRPEI) is a variant of time-resolved photoelectron spectroscopy used in the study of gas-phase photoinduced dynamics. A new observable, time-dependent photoionization-differential cross section provides useful information on wave-packet motions, electronic dephasing, and photoionization ...

Time-resolved photoion and photoelectron imaging of NO2
Physical Chemistry Chemical Physics, 2006Time-resolved photoion and photoelectron velocity mapped images from NO(2) excited close to its first dissociation limit [to NO(X(2)Pi) + O((3)P(2))] have been recorded in a two colour pump-probe experiment, using the frequency-doubled and frequency-tripled output of a regeneratively amplified titanium-sapphire laser.
