TLDR
In this paper, the authors cover the principle of dispersive Fourier transformation and its implementation in diverse applications, such as optical rogue waves and rare cancer cells in blood, as well as their application in real-time instrumentation and measurement.Abstract:
It's challenging to measure non-repetitive events in real time in the field of instrumentation and measurement. Dispersive Fourier transformation is an emerging method that permits capture of rare events, such as optical rogue waves and rare cancer cells in blood. This Review article covers the principle of dispersive Fourier transformation and its implementation in diverse applications.read more
