Optical Waveform Recorder

Modern real-time oscilloscope and high-speed digitizer technology is limited in its performance by relying on electronics for its processing. Optical technology permits much higher performance which permits the measurement of shorter events. There exists a need for an oscilloscope which can measure ultrafast waveforms with a temporal resolution from about 1 ps down to below 100 fs of impulse response width in an expedient and efficient manner.
Patent Abstract: 
The invention relates to a measurement method and system for capturing both the amplitude and phase temporal profile of a transient waveform or a selected number of consecutive waveforms having bandwidths of up to about 10 THz in a single shot or in a high repetition rate mode. The invention consists of an optical preprocessor which can then output a time-scaled replica of the input signal to a conventional oscilloscope for display.
