Which set lists the three sensor modes taught in class?

• A. EO (DTV), Infrared, SWIR
• B. Infrared, SWIR, Visible
• C. EO (DTV), Infrared, LIDAR
• D. EO (DTV), MIR, SWIR

Answer: (A)

This item tests your understanding of the imaging sensor modalities covered in the class. The three modalities are visible electro-optical imaging labeled as EO (DTV), infrared imaging, and SWIR imaging.

EO (DTV) refers to the visible-light, digital television–style imaging channel. It captures detailed, color-rich images under daylight when visible light is plentiful. Infrared imaging detects thermal radiation, providing contrast based on temperature differences and enabling imaging in low-light or no-light conditions. SWIR imaging sits in the short-wave infrared range, offering a balance between visible detail and infrared sensitivity, with the ability to see through some atmospheric interference where visible light struggles.

Why this set fits best: it lists the three sensor modes exactly as taught—visible EO (DTV) for daylight color imagery, infrared for thermal information, and SWIR for specialized infrared imaging. The other options either replace the precise label used in class (EO vs Visible) or mix in an additional modality like LIDAR or a different infrared subdivision (MIR) that isn’t treated as one of the three core sensor modes in this context.
