Abstract

Near-field scattered light, due to ghost images produced from multiple reflections or due to scatter off optical surfaces, will contribute to background noise. This background noise can reduce contrast and blur edge transitions. These sources of background noise cannot be compensated for since they are scene-dependent. High-performance remote sensing instruments, such as the Moderate Resolution Imaging Spectrometer (MODIS), have strict systems-level radiometric performance criteria, such as transient response and stray light, which demand that background noise sources be well controlled. This paper discusses design challenges brought on by these requirements and subsequent modifications and analysis techniques used to minimize ghosting for the MODIS instrument.
