Ultra-fast optical time-domain transformation (UO-TDT) techniques are used to encode spatial and spectral information from ultra-short pulses into the time domain. In this Primer, Zhang et al. cover the physical and mathematical basis of UO-TDT and its application in various imaging platforms, and conclude with an outlook on how these techniques could be applied to novel applications and imaging modalities.
