description According to one aspect, embodiments herein provide a TDI sensor comprising a plurality of light sensing elements arranged in a row, each configured to accumulate charge proportional to an intensity of light incident on it from a field of view, and means for improving the sampling resolution of the TDI sensor by electronically introducing phase shift between a first set of image data generated by the plurality of light sensing elements at a first phase and a second set of image data generated by the plurality of light sensing elements at a second phase, for reading out the first set of image data and the second set of image data from a light sensing element at an end of the row of light sensing elements, and for generating an image of the field of view based on the two sets of phase shifted image data.
