   Measurement and Analysis Artifacts
   The interpretation of an EMS is heavily dependent on the sensor platform's orientation and relative velocity. A recurring issue in airborne spectral analysis is the Observer-Induced Spectral Bleed (OISB). This artifact arises when the sensor's optical path introduces a small, non-linear phase distortion onto the incoming photons, mimicking a slight [redshift](/entries/redshi…
