Abstract

We present a spatial analysis for the Visible (VIS), Near Infrared (NIR), Shortwave Midwave Infrared (S/MWIR), and Long Wave Infrared (LWIR) focal planes of Moderate Resolution Imaging SpectroRadiometer (MODIS) Pre-Flight Model (PFM) on the Terra platform. The analysis includes focal plane detector (channel) alignment, optical/electronic cross-talk, and Far Field Response (FFR). The study is performed on pre-launch laboratory Point Spread Response (PSR) data, and three sets of alignment data both taken prior to August 1998. The PSR and alignment data are displayed using the Focal Plane Viewer (FPV), a software utility developed to aid in the study. Channel measurement and band summaries are presented for each focal plane. The findings for optical/electronic cross-talk are based on the PSR and the alignment data. The calculation of Ensquared Energy (EE) from the PSR data characterizes the far-field response for channel 5.
