What is meant by thermal tuning?

• A. Adjusting the Span Automatically
• B. Adjusting the Span Manually
• C. Changing Emissivity
• D. Calibrating The Detector

Answer: (B)

Thermal tuning is about setting the displayed temperature range to optimize the image. It’s done by manually adjusting the span control, which defines the range of temperatures that map to the image’s brightness. By dialling the span, you tailor the camera’s dynamic range to the scene, making temperature differences more or less visible and improving contrast for the target features. This is distinct from automatic span adjustments, emissivity changes, or detector calibration. Therefore, the action described by thermal tuning is adjusting the span manually.
