The tracker (12) has a target search unit with an illumination unit (25) i.e. LED, for illuminating a target, and first and second cameras (24) e.g. pixel sensor array cameras, for acquiring first and second images, where parts of illumination beams reflected on the target are determinable as first and second target positions. The second camera is arranged or fixed in relation to the first camera such that the fields of vision of the cameras partially overlap, where the target is located in relation to the target positions, when the search function is performed. Independent claims are also included for the following: (1) a method for searching a target (2) a computer program product comprising program codes for performing a method for searching a target. |
