In this paper, we present a new approach to improve an angular resolution of a laser range finder by using a pan unit. In the case of using a laser range finder in large area applications (e.g. map building, detection and tracking of surrounding objects), since a laser range finder radiates laser beams from its center position, the density of the laser beams becomes sparse at a far distance from the laser range finder, which causes the lack of the data points at a far distance. Therefore, we set the pan unit beneath the laser range finder and made it pan by a higher angular resolution than that of the laser range finder and compensated for the lack of data points at a far distance. Experimental results show that we can increase the number of the obtained data points from the laser range finder even if objects are far from the laser range finder.
