Abstract

ATMOS is a Fourier transform spectrometer to measure atmospheric trace molecules over a spectral range of 2-16 μm. Assessment of the system performance of ATMOS includes evaluations of optical system errors induced by thermal and structural effects. In order to assess the optical systemerrors induced from thermal and structural effects, error budgets are assembled during system engineering tasks and line of sight and wavefront deformations predictions (using operational thermal and vibration environments and computer models) are subsequently compared to the error budgets. This paper discusses the thermal/structural error budgets, modelling and analysis methods used to predict thermal/ structural induced errors and the comparisons that show that predictions are within the error budgets and thus the system is predicted to meet requirements.
