Abstract:

Pulsar is a major astronomical event discovered by human beings in the 20th century. X-ray pulsar detection, as one of the important branches of astrophysics and space exploration, plays an important role in the field of basic scientific research and engineering applications, and has long been included in the national major development plan by the United States, Europe, Japan and China. Pulsar detection faces serious problems such as weak self-radiation flow, complex space radiation background, and easy scattering of X-rays, and the high-sensitivity detection of millisecond pulsars is especially extremely challenging. In recent years, the rapid development of X-ray focused optics has provided new methods and perspectives for space astronomy, space science, and pulsar timing and navigation. By reviewing the development process of X-ray focused optics in the past half century, this paper summarizes future pulsar detection demands, and expounds the key technologies, applications and development status of space X-ray focused optics. The future development trend of X-ray focused optical technology and its potential applications in the field of X-ray pulsar detection are also discussed.

Key words: X-ray focused optics, Wolter-Ⅰ, pulsar detection, pulsar navigation, pulsar timing, astrophysics
