Abstract

The invention provides a focusing performance analysis method for a grazing incidence optical system based on X-ray optical simulation. The method fully considers characteristic information of X-ray photon energy and reflectivity, irons out a defect in the prior art that only single-energy X-ray photons are considered and the reflectivity is not considered, can achieve engineering actual condition closer to X-ray pulsar navigation apparatus, and improves the efficiency of X-ray optical simulation and analysis. The method can achieve the analysis of the focusing performance of an optical system under the conditions of thermal deformation, structural deformation or thermal-structural coupling deformation, and obtains the mean square root radiuses of a disc of confusion of the optical system, 100% energy concentration ratio and 50% energy concentration ratio under different conditions, thereby achieving the quantification of impact degree on the focusing performance of the optical system from different deformations, and providing support for the reliability design and optimization of a product.

Description

technical field

[0001] The invention relates to the technical field of spacecraft product design, in particular to a focusing performance analysis method of a grazing incidence optical system based on X-ray optical simulation. Background technique

[0002] Driven by military needs, resource detection and scientific exploration, X-ray pulsar navigation technology has developed rapidly. X-ray pulsar navigator is the core load in this field, and its performance indicators such as spatial resolution, time resolution, and navigation accuracy are constantly improving. The improvement of navigator performance requirements also determines the stability of the optical system and supporting structure of the entire device. The height and size put forward more stringent requirements. At the same time, with the development of small satellite technology, the requirements for the lightweight of X-ray pulsar navigators continue to grow. The design of the X-ray pulsar navigator involves mu...
