抄録

Advances in Fourier optics and information processing technology have facilitated a variety of new research areas in telecommunications, biology, quantum information science, spectroscopy, and atomic and molecular physics. The concept of space-time duality plays an important role as a system design tool for ultrafast optical processing and characterization. In particular, time-lens-based temporal imaging systems enable additional features such as waveform expansion and compression that are particularly useful for ultrafast optical signal processing. The time-equivalent optical setup of a spatial 2-f system, which acts as a Fourier processor (time-to-frequency and frequency-to-time conversion)，can be used as a basic component of more complex temporal imaging systems. This special issue focuses on timestretch spectroscopy, which uses frequency chirp ultrafast laser pulses to capture ultrafast phenomena in real time.
