Ultrabroadband mid-IR continuum pulses can be detected on a single-shot basis using chirped-pulse upconversion. Converting the mid-IR pulse to the visible reduces the fractional bandwidth and enables use of a silicon CCD camera. Removing the cross-phase modulation of the chirped pulse results in 1 cm(-1) resolution over a 600 cm(-1) detected bandwidth.
超宽带中红外连续脉冲可以使用啁啾脉冲上转换在单次测量的基础上进行探测。将中红外脉冲转换到可见光波段可以降低分数带宽，并使用硅 CCD 相机。消除啁啾脉冲的交叉相位调制，在 600 cm(-1) 的检测带宽内可以获得 1 cm(-1) 的分辨率。
