Time-stretch infrared spectroscopy (TSIR) has been developed as a high-speed single-shot infrared spectroscopy method. Conventially, TSIR can only access the intensity information of the mid-infrared spectra.In this work, we present a pulse-to-pulse mid-infrared spectral phase measurement technique based on upconversion time-stretch spectroscopy (UC-TSIR) interferometry. This work could be a powerful upgrade to TSIR.
