What is NUC?

NUC (Non-Uniformity Correction) is a calibration process used in thermal imaging to correct pixel inconsistencies and improve image quality.

Why is NUC Important?

Each pixel in a thermal sensor reacts differently to temperature, which can cause noise and uneven images. NUC ensures a uniform and accurate image.

How Does NUC Work?

NUC uses a uniform reference—usually by blocking the lens—to recalibrate the sensor and correct deviations.

Role of Optical Shutter

Optical shutters play a key role by blocking infrared input and providing a stable reference for accurate calibration.

Auto vs Manual NUC

NUC can be automatic (periodic) or manual (user-triggered), depending on the system design.

What Will You Notice?

During NUC, the image may freeze briefly and a clicking sound may occur due to the shutter.

NUC is essential for maintaining accurate and stable thermal imaging performance.
