光子时间拉伸（PTS）技术可在超快电子和光学系统中实现革命性的技术突破。通过利用大色散将超短光脉冲的频谱映射到拉伸的时域波形（即使用色散傅里叶变换），PTS克服了传统技术的根本速度限制。PTS中使用的色散可以使用多个光学棱镜阵列来实现，其具有特定电信频段之外的扩展频谱低损耗、灵活性和成本效益等独特优势。在这篇文章中，我们提出并证明了PTS技术建立了一对棱镜，这是一种数据采集方法，在超快的数字化，成像和测量制度。
Photonic time-stretch (PTS) technology enables revolutionary technical breakthroughs in ultrafast electronic and optical systems. By means of employing large chromatic dispersion to map the spectrum of an ultrashort optical pulse into a stretched time-domain waveform (namely, using the dispersive Fourier transformation), PTS overcomes the fundamental speed limitations of conventional techniques. The chromatic dispersion utilized in PTS can be implemented using multiple optical prism arrays, which have the particular advantages of low loss in the extended spectrum outside of the specific telecommunication band, flexibility, and cost-effectiveness. In this article, we propose and demonstrate the PTS technology established for a pair of prisms, which works as a data acquisition approach in ultrafast digitizing, imaging, and measurement regimes.
