Study on self-triggered instantaneous gating imaging of waveguide grating microarray (invited)

In view of many technical constraints and techcical bottlenecks in traditional gating imaging system, a novel self-triggering instantaneous gating imaging of waveguide grating microarray that considered self-triggered gating and instantaneous imaging was proposed. This article not only showed a complete self-triggered gating imaging principle and device model, but also explained the advantages of quantum dot films based on perovskite in transient gating imaging. In the end, the spatial modulation effect of waveguide gratings microarray, electron beams, electronically pumped imaging and the instantaneous luminescence effect of quantum dot film based on perovskite, were calibrated and modeled in the vacuum test system. The feasibility of the technical scheme was proved by experiments.
