Images with linear response have become the backbone of the imaging industry. But each pixel of the TDI CCD has unique light sensitivity characteristics. Because these characteristics and the lens of the optical system affect camera's linearization and its performance  they must be removed through calibration. The process by which a CCD image is calibrated is known as nonuniformity correction. This paper discusses several methods of nonuniformity correction[2]. The first is one-point correction technique  which requires only one calibration point. This approach is to shift each curve toward the nominal curve by subtracting the offset from or adding the offset to the average. The second is two-point correction technique  which requires two calibration points. Each point is rotated and aligned so that all the detectors have the same response under the same radiance. The third is multipoint correction. It is recommended that more calibration points be implemented at appropriate regions of the response curve. Depend on the linear photoelectric response of the TDI CCD  we use two-point calibration and the standard deviations for the images are given before and after the correction.   Investigation on drilling-induced delamination of CFRP with infiltration method (EI收录) 会议论文 Advanced Materials Research, Guangzhou, China, December 7, 2010 - December 9, 2010 作者:  Quan, Yanming[1];  Sun, Luhua[1] 收藏  |  浏览/下载：1/0  |  提交时间：2019/04/16 Carbon fibers  Chlorine compounds  Delamination  Drilling  Drills  Fiber reinforced materials  Industrial engineering  Inspection  Manufacture  Mechanical properties  Plastics  Seepage  Soil mechanics  Steel sheet  Vehicular tunnels
