Abstract

The FORUM Sounding Instrument (FSI) is a step-and-stare Fourier-transform infrared spectrometer that performs radiometry on light leaving the earth within a spectral range from 6.25 to 100 μm. During the scan of the pendulum-type interferometer, the light intensity at the two output ports is recorded by a detection chain based on modified component-off-the-shelf pyroelectric detectors. This paper reports on fundamental detector properties and the results of electro-optical characterization. In contrast to the majority of established literature, the characterization was performed using visible light permitting a high degree of control over geometric and modulation properties of the optical stimulus. The results significantly contributed to a thorough understanding of the detector and the choice of the best design for the FORUM mission. This paper represents the status of the work at the start of project phase B2.
