“…All-optical mapping photography [1][2][3] has the advantages of high time resolution, high luminous flux, and anti-radiation interference and can effectively overcome the shortcomings of the pump-probe technique [4,5], which is unable to perform non-repeatable or difficult-to-replicate event observation. Meanwhile, it can also avoid the drawbacks of low spatial resolution and complex image reconstruction from compressed ultra-fast spectroscopy [6,7] and multi-spectral tomography [8].…”

“…This system has the advantages of fewer optical elements and a compact structure; however, the fabrication of diffractive optical elements was challenging and expensive, and lower energy utilization and poor consistency of 2D diffraction efficiency limit the further development of this system. Saiki et al used slicing mirrors instead of the periscope array for complete optical field control [19], which was then developed by Yuan et al [2,20,21]. This can effectively increase the frame and detector utilization of the instrument; however, there are problems, such as the high precision of the grating and the slice mirror and the existence of chromatic aberration that reduces the quality of imaging.…”

Sequentially timed all-optical mapping photography is one of the main emerging ultra-fast detection technologies that can be widely applicable to ultra-fast detection at the picosecond level in fields such as materials and life sciences. We propose a new optical structure for an all-optical spatial mapping module that can control the optical field of two-dimensional imaging while improving spectral resolution and detector sensor utilization. The model of optical parameters based on geometrical optics theory for the given structure has been established, and the theoretical analysis of the inter-frame energy crosstalk caused by incident beam spot width, chromatic aberration, and main errors of the periscope array has been conducted. The optical design of the two-dimensional (2D) all-optical spatial mapping module was finally completed using ZEMAX OpticStudio 2018 software. The results show that our optical module can realize targets of 16 frames and 1.25 nm spectral resolution.

Due to the lack of theoretical research on the amount of spatio-temporal information in high-speed photography technologies, obtaining an optimized system with the best amount of spatio-temporal information remains a challenge, resulting in insufficient effective information and observation accuracy for ultrafast events. This paper presents an ultrafast raster imaging (URI) system with a large amount of spatio-temporal information based on the all-optical raster principle in single-shot. Specifically, we derive the optimal equation of spatial resolution and the expression for the maximum amount of spatio-temporal information that can achieve excellent performance for a URI system. It serves as a general guideline for obtaining a large amount of information design in the URI system. Compared with the existing URI systems, the advanced URI system exhibits an improvement of nearly one order of magnitude in the amount of spatio-temporal information and more than twofold in spatial resolution. It shows great potential for capturing intricate and non-repetitive ultrafast events on the femtosecond time scale.

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 μm and a frame rate of 2.5 Tfps, indicating its potential for the observation of highly dynamic events.
