Abstract

The high dynamic range of naturally occurring atmospheric emissions can present a serious challenge to infrared instrumentation designers. The requisite optical filters have out-of-band rejection requirements that are beyond the capability of the standard measuring techniques. While the filter manufacturers can predict their filter performance to more than seven orders of magnitude, their measurement capability is limited to about four orders. The Space Dynamics Laboratory has recently tested a new measurement method which employs a cascaded test filter and a Michelson interferometer spectrometer.
