Sequentially timed all-optical mapping photography with quantitative phase imaging capability

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.
