Jingzhen Li, Yi Cai, Xuanke Zeng +3
Atomic time scale imaging, opening a new era for studying dynamics in microcosmos, is presently attracting immense research interesting on the global level due to its powerful abil…
Single-shot framing integration photography with high spatial resolution at 5.3*1012 frames per second by an inversed 4f system
Qifan Zhu, Yi Cai, Xuanke Zeng +5
We present a framing integration ultrafast photography (FIP), which integrates the framing structure, codes a dynamic event by an inversed 4f system (I4F) and decodes regionally wi…
Ultrafast Framing Imaging utilizing Multiple Optical-parametric-amplification with High Spatial Resolution and Imaging Rate
Xuanke Zeng, Shuiqin Zheng, Yi Cai +6
The discovery and understanding of many ultrafast dynamical processes are often invaluable. This paper is the first report to apply optical parametric amplification to implement si…
Orthogonality of Diffractive Deep Neural Networks
Shuiqin Zheng, Xuanke Zeng, Lang Zha +3
Several laws are found for the Diffractive Deep Neural Networks (D2NN). They reveal the inner product of any two light fields in D2NN is invariant and the D2NN act as a unitary tra…
High-resolution single-shot ultrafast imaging at ten trillion frames per second
Xuanke Zeng, Yi Cai, Shuiqin Zheng +6
Ultrafast imaging is a powerful tool for studying space-time dynamics in photonic material, plasma physics, living cells, and neural activity. Pushing the imaging speed to the quan…
