Imaging properties of a Wolter-I type X-ray telescope with particular reference to contrast reduction through diffuse reflection
Abstract
Theoretical and experimental results are presented on the geometrical-optic imaging properties of a Wolter-I type paraboloid-hyperboloid X-ray telescope. Particular consideration is given to the effect of microroughness of the mirror on the imaging properties. Experiments were conducted in which scattering properties were determined as a function of wavelength, incidence angle, and roughness of the plane mirrors. Results indicate the need for optimization of mirror material and polishing technology as well as the development of improved mirror manufacturing techniques. The use of transmission gratings along with the Wolter-I type telescope in spectroscopy applications is discussed.
