Abstract:
1. A method of measuring a temporal waveform of a pulse, the method comprising: obtaining a Fourier transform magnitude of the temporal waveform of the pulse; obtaining a Fourier transform magnitude of a reference temporal waveform of a reference pulse; obtaining a Fourier transform magnitude of a first composite temporal waveform of a first composite pulse comprising the pulse followed by the reference pulse; obtaining a Fourier transform magnitude of a second composite temporal waveform of a second composite pulse comprising the pulse followed by a time-reversed pulse having a time-reversed temporal waveform corresponding to the reference temporal waveform after being time-reversed; calculating the temporal waveform using the Fourier transform magnitude of the temporal waveform, the Fourier transform magnitude of the reference temporal waveform, the Fouler transform magnitude of the first composite temporal waveform, and the Fourier transform magnitude of the second composite temporal waveform; and using the calculated temporal waveform to provide information regarding the temporal waveform of the pulse.
