A Space Neutral Atom Imaging Device

Abstract

The invention provides a spatially neutral atom imaging device, which includes several imaging units distributed along the circumferential direction, and the included angles between adjacent imaging units are the same; the imaging unit includes: a collimator, a deflection electrode plate, a semiconductor sensor and the code modulation plate, the collimator, the code modulation plate, the deflection electrode plate and the semiconductor sensor are sequentially connected from top to bottom, the semiconductor sensor and the code modulation plate are arranged in parallel, and the deflection electrode plates are paired and parallel It is arranged between the semiconductor sensor and the code modulation plate, and the deflection electrode plate is perpendicular to the code modulation plate. Using this device to improve the spatial and temporal resolution of imaging, the grid is used to modulate the particle flow intensity in all directions in space. Under the same weight and volume of the neutral atom imager of the separation measurement method, better spatial resolution and time resolution are obtained.

Description

technical field [0001] The invention relates to the technical field of space detection, in particular to a space neutral atom imaging device. Background technique [0002] Advances in space environment science research indicate that space weather changes, especially magnetospheric substorms and magnetic storms, are characterized by global evolution. The plasma detection in the satellite local space only reflects the physical characteristics of the area the satellite passes through, and has both spatial and temporal variation factors. Spatial probing requirements for evolving physical signatures. For the particle response energy range and specific space regions, the development of particle imaging detection technology with telemetry function is an urgent requirement for space physics research and space weather environment monitoring. [0003] Neutral atom imaging is a high-tech application in space exploration in recent years, and it is currently the only way to visualize t...
