Characterization of space X-ray reflective focusing system by using synchrotron radiation facility

Abstract

Considering the urgent demand for the testing and calibration of X-ray space telescope in the fields of pulsar observation and timing navigation，this review summarizes various high-precision wavefront and mirror figure detection，system calibration and reflectivity test techniques using synchrotron radiation and free electron laser facilities. Some important at-wavelength metrologies for testing reflective mirrors with different scales and surface shapes，such as pencil beam，Hartmann sensor，grating interferometer and near-field speckle techniques，are introduced and compared. The current application of synchrotron radiation facility in at-wavelength imaging，calibration and reflectivity measurement of X-ray space telescope is also presented. The characterization of space telescope based on synchrotron radiation is hoped to be widely developed，so as to promote further progress of related fields. The blooming synchrotron radiation facilities provide potential strong support for wavelength detection，calibration and optical performance characterization for large-scale X-ray space telescope.
