Sequentially timed all-optical mapping photography (STAMP) is considered a powerful tool to observe highly dynamic events; however, its application is significantly hindered by its incapability to acquire quantitative phase images. In this work, by integrating diffraction phase microscopy (DPM) and STAMP, we achieve ultrafast single-shot quantitative phase imaging with a frame rate of up to 3.3 trillion fps. The performance of the system is evaluated using a homemade phase module. Experimental results show that the system can accurately record the propagation of laser filamentation in air. We believe our method will greatly enhance the capability of STAMP to measure highly transparent targets.
顺序定时全光学映射摄影（STAMP）被认为是观察高动态事件的强大工具；然而，由于其无法获取定量相位图像，其应用受到了显著阻碍。在这项工作中，通过将衍射相显微镜（DPM）与STAMP相结合，我们实现了高达3.3万亿帧每秒帧率的超快单次定量相位成像。使用自制的相位模块对该系统的性能进行了评估。实验结果表明，该系统能够准确记录空气中激光丝的传播。我们相信我们的方法将大大提高STAMP测量高透明目标的能力。
