Ultrafast NMR based on spatial encoding yields arbitrary multidimensional spectra in a single scan. The dramatic acceleration afforded by parallelisation makes it possible to capture transient species and processes, has notably been applied the monitoring of reactions analysis hyperpolarised species. At heart ultrafast lies spatially sequential manipulation nuclear spins. This is virtually alwa...

A linearized wavelength-swept thermo-optic laser chip was applied to demonstrate a fiber Bragg grating (FBG) sensor interrogation system. A broad tuning range of 11.8 nm was periodically obtained from the laser chip for a sweep rate of 16 Hz. To measure the linear time response of the reflection signal from the FBG sensor, a programmed driving signal was directly applied to the wavelength-swept...
