The X-ray lobster eye lens, an innovative technique for focusing high-energy radiation, enables wide-field X-ray imaging. However, its inherent cross point spread function introduces noise and degradation into the resultant images. Conventional image restoration methods are inadequate for suppressing such noise.

All square microchannels point to the same spherical center position, providing a wide field of view and high focusing and imaging capabilities. Enhancing the optical performance of MPO has been a significant challenge.

Article Synopsis
- The Lunar Environment heliospheric X-ray Imager (LEXI) is a soft X-ray telescope designed for studying how solar wind interacts with the Earth’s magnetosphere as part of the Blue Ghost 1 mission, which includes 10 payloads on the lunar surface.
- LEXI focuses on capturing soft X-rays emitted during solar wind interactions, to observe the position and shape of the magnetopause over time.
- Using lobster-eye optics, LEXI has a wide 9.1-degree field of view, allowing it to image magnetic reconnection phenomena in detail.
In contrast to conventional X-ray imaging systems, the lobster eye lens, serving as a pivotal component for X-ray focusing, presents the potential for downsizing X-ray backscatter imaging systems. This study reports the successful implementation of a pioneering non-contact staring X-ray backscatter imaging experiment, with the target positioned 1.5 meters away from the system and employing a tube voltage of 60 kV for the X-ray light source.
