Space Telescopes and Instrumentation 2014: Optical, Infrared, and Millimeter Wave
The Primordial Inflation Explorer is an Explorer-class mission to measure the gravity-wave signature of primordial inflation through its distinctive imprint on the linear polarization of the cosmic microwave background. PIXIE uses an innovative optical design to achieve background-limited sensitivity in 400 spectral channels spanning 2.5 decades in frequency from 30 GHz to 6 THz (1 cm to 50 micron wavelength). Multi-moded non-imaging optics feed a polarizing Fourier Transform Spectrometer todoi:10.1117/12.2056840 fatcat:ikbkfoq5tjbp5nk5gbwdafbzke
