Sources of attosecond-duration light pulses provide the fastest time resolutions available today for observing ultrafast phenomena in atoms, molecules and condensed matter. The measurement of such ...

Pulse measurement equipment is now easier to use than ever before, with many devices offering easy-to-align solutions and plug-and-play computer operation, reports Neil Savage. Ultrafast lasers, which ...

The increased pulsation of arteries in the brain is closely linked to cognitive impairment, and some scientists think it ...

Researchers have developed a time-domain single-pixel imaging technique to speed the measurement of ultrafast pulses in infrared and far infrared wavelengths. When we look at an object with our eyes, ...

Using a spectrum analyzer for pulsed measurements has always required a careful understanding and knowledge of the parameters of the pulse signal, as well as the subsequent operation of the spectrum ...

Generating ultrashort laser pulses that last a few femtoseconds is a highly active area of research that is finding applications ranging from micromachining to eye surgery. For optimum results it is ...

Researchers at USC have created the first method to noninvasively measure microscopic blood vessel pulses in the human brain. Using advanced 7T MRI, they found these tiny pulsations grow stronger with ...

Lasers that transmit data on optical fibers do not produce monochromatic light. Instead, they provide a narrow spectrum that includes many wavelengths. The physical characteristics of optical fibers ...

A time domain reflectometer (TDR) measures reflections along a cable. It is similar in principle to radar. To measure those reflections, the TDR transmits an incident signal into the cable and watches ...
