Which of the following lists the three types of NUCs?

Explanation:
Nonuniformity correction (NUC) types are categorized by how the sensor’s irregular pixel responses are addressed. The three recognized forms in this context are Paddle NUC, No Paddle NUC, and Defocus NUC. A Paddle NUC uses a physical calibration paddle to present a uniform reference field across the detectors, enabling correction. No Paddle NUC refers to methods that perform calibration without any paddle, relying on alternative references or internal data. Defocus NUC employs deliberate optical defocus to average pixel responses, producing the correction needed for uniform output. Other terms like Tilted or Focus NUC aren’t part of the standard grouping, so they don’t fit the established three-type set. Therefore, Paddle NUC; No Paddle NUC; Defocus NUC is the correct listing.
