optical pulse

optical pulse

[′äp·tə·kəl ′pəls]
(optics)
A short flash of light, used to isolate moments of time; pulses as short as 15 femtoseconds have been generated with laser and pulse compression techniques.

2) Software-defined pulse shaper: An optoelectronic device that changes the shape of an optical pulse according to values predefined by the user.
After completing the first scan with a short-duration optical pulse, a longer-duration pulse is selected to provide additional optical power to test further along the fiber.
Optical pulse propagation in whispering-gallery modes of liquid spheres has been studied in the time domain.
Furthermore, the fracturing of a rock sometimes produces not only the optical pulse but also "a curious radio emission" with frequencies ranging from about 900 to 5,000 hertz, Zito says.
Contract notice: Finding a suitable light source, study and construction of a optical pulse train generator picoseconds.
Objective: In the framework of signal transport, photonics has already demonstrated its superior performance over electronic approaches and it is therefore critical that short optical pulse monitoring will be capable of measuring an optical signal in its whole complex nature i.
IMRA's turnkey fiber lasers with compact packaging, high stability and maintenance-free operation, are ideal optical pulse sources for material processing, semiconductor inspection and repair, homeland security, instrumentation, medical diagnostics and therapy, and telecommunications.
The researchers eventually read out the spin with yet another optical pulse.
He has made important accomplishments in such diverse areas as light scattering from semiconductors and liquid helium, laser diagnostics of tokomak plasmas for fusion studies, squeezed state generation and the application of squeezed states to sensitive measurement, whispering-gallery mode microdisk lasers, and optical pulse propagation in nonlinear media.
A: An optical mouse works by sending a single LED infrared optical pulse out (a red flash of light), which is then measured by a small sensor (basically a low resolution high zoom camera).
NZDF technology allows engineers to optimize dispersion - the "spreading" of a sharply defined optical pulse as it travels down a fiber - in a manner that enables high bit rate transmission; a total suppression of dispersion is not desirable for DWDM systems.
