摘要：

Sequentially timed all-optical mapping photography (STAMP) is a promising technology for observing ultrafast phenomena. Increasing the frame number during one shot is critical to enhance the capability of STAMP, but the rearrangement of the frames significantly intensifies the complexity of the system. In this work, we design a spectrum-slicing method, allowing for the separation and arrangement of the frames simultaneously in a two-dimensional manner. The experimental results show that our system can capture 25 images in one shot with a spatial resolution of 2.46 mu m and a frame rate of 2.5 Tfps, indicating its potential for the observation of highly dynamic events.
