Abstract

In the great space observatories (the Hubble, the SIRTF), a large-diameter telescope is used to gather the light and deliver it to several instruments. When the telescope entrance pupil is imaged on the secondary mirror of the imaging camera, the aberrations of these two components can be corrected. An adaptive component may be used for the secondary mirror of the high resolution imaging camera to correct the aberrations on the telescope primary mirror for varying amounts of symmetrical (spherical) and asymmetrical (astigmatism) aberration. The Hubble space telescope and the wide-field planetary camera optical system with a single adaptive component will be modeled by using glad to show the feasibility of the adaptive optics to in-orbit aberration correction.
