Navy Department, Beijing 100071, China; 2. Naval Aeronautical and Astronautical University, Yantai 264001, China) Abstract: A complete infrared imaging system contains a number of subsystems for processing different information. The processing and reconstruction process for a scanned image is discussed. The character- istics of single-point and two-point correction methods for eliminating fixed pattern noise are analyzed. The improvement effectiveness of an infrared imaging system after a reference blackbody is included in its scanning system is presented. Finally, the image processing and reconstruction process is summarized systematically. Key words: scanning image; two-point correction; image processing; reconstruction 0 [1] 125% 49% (Nonuniformity, NU) [2] (NUC) 2014–06–25 (1973-) E-mail: 996563996@qq.com http://journal.sitp.ac.cn/hw Infrared (monthly)/Vol.35, No.8, Aug 2014 2 2014 8 [3] [4] [5] 1 / 1(a) / 1(b) I1 I2 I3 [1] 1 2 / (a) (b) 1 (D1 D2 D3) Æ ( ) 2 Æ ( 3 ) 5 [6,7] 3∼ 5 Infrared (monthly)/Vol.35, No.8, Aug 2014 http://journal.sitp.ac.cn/hw 35 8 3 ( NEDT MRT MDT) 3 4 5 Æ Æ Æ ( ) ΔT 5 Æ 6 1/f 1/f 6 2 [8] ( 7) ( ) http://journal.sitp.ac.cn/hw Infrared (monthly)/Vol.35, No.8, Aug 2014 4 2014 8 7 ( 1) VANALOG V IDEO = V ( 1 y ) IN (1) L = K(Vana video)y = K(V ( 1 y ) IN )y = KVIN (2) 3 D/A [9] NL 9MHz Æ [10] Æ Æ Æ 1:1 RS170 (4:3 ) 4:3 1:1 4 A/D 8 / Æ D/A 8 9 Infrared (monthly)/Vol.35, No.8, Aug 2014 http://journal.sitp.ac.cn/hw
