METHOD FOR CONTROLLING TIME DELAY AND INTEGRATION IMAGING AND AN IMAGING SENSOR FOR TIME DELAY AND INTEGRATION IMAGING

摘要

A method for controlling time delay and integration, TDI, imaging includes acquiring image information using an array of pixels being arranged in rows and columns. Each pixel is configured to generate an electric charge proportional to intensity of electro-magnetic radiation incident on the pixel. The pixels are configured to transfer generated charges along columns of the array for accumulating the generated charges in the pixels along the columns from a first row towards a second row in the array of pixels. The method further includes non-destructively sensing, at an intermediate row between the first and the second row, a signal level of accumulated charges in at least one column; and destructively sensing, at the second row, a signal level of accumulated charges in the at least one column.
