Device and method for calculating the destination point of an observation unit, in particular of a firearm simulator

摘要

The system to determine a target (03) at an observation unit (09) has a scanning line projector (06) to give two non-parallel scanning lines (05a,05b) simultaneously or in a time shift to cover a target zone (02) to be moved by a control unit (07). An optical target detector (08) transmits a target signal to the control when a scanning line is recognized. The control determines the position of each scanning line at the time of detection to give the intersection of the scanning lines at this time point as the target point.
