摘要

Aperture diffraction、 geometric aberrations、 surface scatter and other errors (setting errors 、 environmental errors) are several influencing factors on imaging performance of optical system. Especially for short wavelength imaging systems, Surface scattering effects is one of mainly influencing factors which is severely degraded imaging performance. It is necessary that study surface scattering phenomenon to development of short wavelength optics. In this paper, aim at space solar telescope, effect of surface scattering on imaging performance of the grazing incidence systems is evaluated. By combining these scattered light distributions of super-smooth surfaces measured by a soft X-ray reflectometer, and surface scattering numerical model of grazing incidence imaging system, PSF and encircled energy of optical system of space solar telescope are computed. We can conclude that surface scattering severely degrade imaging performance of grazing incidence systems through analysis and computation.
