Wide Field Infrared Survey Telescope WFIRST: telescope design and simulated performance

摘要

The Wide Field Infrared Survey Telescope (WFIRST) mission concept was ranked first in new space astrophysicsmissions by the Astro2010 Decadal Survey, incorporating the Joint Dark Energy Mission payload concept and multiplescience white papers. This mission is based on a space telescope at L2 studying exoplanets [via gravitationalmicrolensing], probing dark energy, and surveying the near infrared sky. Since the release of the Astro2010 DecadalSurvey, the team has been working with the WFIRST Science Definition Team to refine mission and payload concepts.We present the current interim reference mission point design of the payload, based on the use of a 1.3m unobscuredaperture three mirror anastigmat form, with focal imaging and slit-less spectroscopy science channels. We also presentthe first results of Structural/Thermal/Optical performance modeling of the telescope point design.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
