Sampling rate (sometimes called sampling frequency or F s) is the number of data points acquired per second. A sampling rate of 2000 samples/second means that 2000 discrete data points are acquired
A novel approach for a simple all-optical sampling is to utilise the frequency-time coherence of each signal.
