The invention relates to a laser target seeker device arranged to receive a, from an object, reflected laser beam, said device comprising detector elements (12) arranged to detect the reflected laser beam (6), and processing means (30) arranged to determine the received radiation on the respective detector element (12) in order to determine the origin of the laser beam (6), wherein diffraction means (20; 70) are arranged relative to the detector elements (12) and configured to diffract the reflected laser beam (6) into portions (6a, 6b, 6c, 6d) prior to being detected by the detector elements (12), the detector elements being arranged to detect the respective portion. The invention further relates to a flyable body for hitting a target by means of a laser beam. The invention still further relates to a system for hitting a target by means of a laser beam. The invention also relates to a method for detecting a from an object reflected laser beam. In addition the invention relates to use of a kinoform member in a laser target seeker for diffracting a laser beam.
