Spherical Primary Optical Telescope (SPOT): An Architecture Demonstration for Cost-effective Large Space Telescopes
AbstructThis paper summarizes efforts underway at the Goddard Space Flight Center to demonstrate a new type of space telescope architecture that builds on the ria& segmented telescope heritage of the James Webb Space Telescope but that solves several key challenges for future space telescopes. The architecture is based on a costeffective segmented spherical primary mirror combined with a unique...
متن کاملTestable lightweight telescopes for space
The next generation of larger space optics will need lightweight and deployed mirror systems in order to control costs and fit within current and planned launch vehicle fairings. These will require active control based on wavefront sensing to establish and maintain their optical quality. Such control has been the enabling factor for the current generation of 8 m class ground-based telescopes, w...
متن کاملAn Efficient Method for Model Reduction in Diffuse Optical Tomography
We present an efficient method for the reduction of model equations in the linearized diffuse optical tomography (DOT) problem. We first implement the maximum a posteriori (MAP) estimator and Tikhonov regularization, which are based on applying preconditioners to linear perturbation equations. For model reduction, the precondition is split into two parts: the principal components are consid...
متن کاملMirror Design For Optical Telescopes
The reflectormirror is the most important component of an astronomical optical telescope. This chapter provides discussions on the requirements for astronomical optical mirrors; the ways to reduce mirror weight, mirror cost, and mirror materials; the methods of mirror figuring, polishing, and surface coating; the design of mirror support mechanism; the concept of mirror seeing; and the stray li...
متن کاملLaser ray-tracing method for optical testing.
We have developed a novel laser ray-tracing method to measure aberrations in optical systems. It consists of delivering narrow laser pencils (by a laser scanner), recording the spots that are formed on the image plane (with a CCD camera), and computing the position of each centroid. This approach could be considered an experimental (approximate) implementation of standard numerical ray tracing....
