Abstract: 
This paper summarizes the TIDI instrument performance as 
installed on the TIMED spacecraft, now awaiting launch in 
early 2001.  TIDI will measure winds, temperatures and minor 
constituent densities in the 60-300 km altitude range by 
resolving line shapes and Doppler shifts of emission lines 
in the 550-900 nm spectral region.  The TIDI Profiler uses a 
single-etalon Fabry Perot Interferometer (FPI), Circle-to-
Line-Interferometer Optic (CLIO), and CCD detector.  Key 
measures of optical performance, and the resulting expected 
sensitivity to terrestrial airglow emissions, are reported.
