Autor: 陈浠惠 Chen Xi-hui, 冷雪 Leng Xue, 张雪菲 Zhang Xuefei, 孙翠羽 Sun Cui-yu, 李文明 Li Wen-ming
Publikováno v: Optics and Precision Engineering. 22:467-473
When a long focal area-array CCD camera takes photos in a TDI mode for dynamic lateral multi-frame imaging, it will output images with large size defect on the edge of image because of the high line transfer frequency or long exposure time and will i
