WebFlat-field correction (FFC) is a technique used to improve quality in digital imaging. It cancels the effects of image artifacts caused by variations in the pixel-to-pixel sensitivity of the detector and by distortions in the optical path. It is a standard calibration procedure in everything from personal digital cameras to large telescopes. WebThe flatness of the wafer can be described either by a global flatness value or as the maximum value of site flatness. The reference plane can be chosen in several different ways, depending on the parameter measured: • three points at specified locations on the front surface; • least square fit to the front surface; •
