Rapid-scan acousto-optical delay line with 34 kHz scan rate and 15 as precision

Ultrafast time-domain spectroscopy system using 10 GHz asynchronous optical sampling with 100 kHz scan rate.

An ultrafast time-domain spectroscopy system employing asynchronous optical sampling at a repetition rate of 10 GHz is presented. Two ultra-compact Ti:sapphire femtosecond ring lasers allow to achieve scan rates as high as 100 kHz for a 100 ps long time window and a time-delay resolution of 100 fs. The feasibility of this high-speed ASOPS system is evaluated by performing THz time domain spectr...

Scan Based Delay Testing

Scan Based Delay Testing is used to perform delay testing in the sequential circuits which have the scan capability. In this paper, basics of delay testing and several techniques to perform delay testing for scan based circuits are discussed. The construction of several scan flip-flops along with their advantages and disadvantages is also presented.

Rapid-scan EPR imaging.

In rapid-scan EPR the magnetic field or frequency is repeatedly scanned through the spectrum at rates that are much faster than in conventional continuous wave EPR. The signal is directly-detected with a mixer at the source frequency. Rapid-scan EPR is particularly advantageous when the scan rate through resonance is fast relative to electron spin relaxation rates. In such scans, there may be o...
