Abstract
an optical sensing system comprising: a processing circuit; a first calibration optical sensor, comprising a first sensor edge and a second sensor edge opposite to the first sensor edge; and a second calibration optical sensor, away from the first calibration optical sensor for a first distance, comprising a third sensor edge and a fourth sensor edge opposite to the third sensor edge. The processing circuit determines a target object has moved for a target distance if an object pattern of the target object moves from a first location in the first calibration sensor to a second location in the second calibration sensor, wherein a first sum of a second distance which is between the first location and the first sensor edge and a third distance between the second location and the third sensor edge equals to a reference distance.
