Abstract
The present disclosure provides a time delay integration (TDI) sensor using a rolling shutter. The TDI sensor includes two pixel arrays each having multiple pixel columns. Each pixel column includes multiple pixels arranged in an along-track direction, wherein two adjacent pixels or two adjacent pixel groups in every pixel column have a separation space therebetween. The separation space is equal to a pixel height multiplied by a time ratio of a line time difference of the rolling shutter and a frame period, or equal to a summation of at least one pixel height and a multiplication of the pixel height by a time ratio of the line time difference and the frame period. The TDI sensor doubles a number of times of integrating pixel data corresponding to the same position of a scene by arranging two separately operated pixel arrays.
