Time-resolved spectroscopy of the human forearm

Journal of Photochemistry and Photobiology B: Biology, 1992
For spectroscopic purposes, the forearm is a conveniently large object to be investigated because consistent oxygenation and blood volume changes can be obtained. Human forearm spectral properties were investigated using picosecond near-IR laser spectroscopy. The behaviour of the temporal point spread function in resting conditions and during ischaemia,

Time-Resolved Photochemistry of Stiffened Stilbenes

The Journal of Physical Chemistry B, 2019
Broadband transient absorption spectroscopy is used to study the photoisomerization of stiffened stilbenes in solution, specifically E/ Z mixtures of bis(benzocyclobutylidene) (t4, c4) and ( E)-1-(2,2-dimethyltetralinylidene)-2-2-dimethyltetraline (t6). Upon excitation to S1, all evolve to perpendicular molecular conformation P, followed by decay to S0,

Time-resolved fluorescence spectroscopy

Current Opinion in Structural Biology, 1996
Time-resolved fluorescence spectroscopy is used to monitor molecular interactions and motions that occur in the picosecond-nanosecond time range, and is especially useful in the analysis of biomolecular structure and dynamics. Recent advances in the application of time-resolved fluorescence spectroscopy to biological systems have led to a better ...

Time-resolved holography

Nature, 1991
IN a conventional hologram, a photographic film records the interference pattern of monochromatic light, scattered from the object to be imaged, with a reference beam of unscattered light. Illumination of the developed film with a replica of the reference beam then creates a virtual image of the original object.

Time Resolved Microfluorescence In Biomedical Diagnosis

Optical Engineering, 1985
A measuring system combining subnanosecond laser-induced fluorescence with microscopic signal detection was installed and used for diverse projects in the biomedical and environmental fields. These projects range from tumor diagnosis and enzymatic analysis to measurements of the activity of methanogenic bacteria, which affect biogas production and ...

Time-resolved Diffraction

1997
Abstract In recent years technological advances in synchrotron and neutron sources, detectors, and computer hardware and software have allowed diffraction techniques to advance to a stage where data can be collected on a system with time.

Computational time-resolved imaging.

2015
Classical photography uses steady-state illumination and light sensing with focusing optics to capture scene reflectivity as images; temporal variations of the light field are not exploited. This thesis explores the use of time-varying optical illumination and time-resolved sensing along with signal modeling and computational reconstruction.
