End-to-end simulation of high-contrast imaging systems: methods and results for the PICTURE mission family
(SPIE, 2015-09)We describe a set of numerical approaches to modeling the performance of spaceflight high-contrast imaging payloads. Mission design for high-contrast imaging requires numerical wavefront error propagation to ensure accurate ... -
Asymptotic analysis of numerical wave propagation in finite difference equations
(Cambridge, Mass. : Gas Turbine & Plasma Dynamics Laboratory, Massachusetts Institute of Technology, [1983], 1983)An asymptotic technique is developed for analysing the propagation and dissipation of wave-like solutions to finite difference equations. It is shown that for each fixed complex frequency there are usually several wave ... -
A numerical analysis of 3-D inviscid stator/rotor interactions using non-reflecting boundary conditions
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1992], 1992)This dissertation presents a method for the computation of three-dimensional inviscid, transonic steady and unsteady flows, primarily in axial flow turbines. The work is divided into two major contributions. The first is ...
