An optical discrete time-frequency domain transform technology is proposed for ultra-fast optical waveform measurements. By using the technology, single shot ultrafast optical phenomena in a long time frame would be captured without missing. I will also demonstrate that the technology is to be implemented in some measurement system based on the linear behavior of the transformation. This measurement platform will open the door for ultrafast optical measurements in several areas.
