Abstract:
A test installation (10) for a target tracking system (20, 30) having a scanner device (30); a selectively light-transmissive or reflective projection wall (24) arranged in spaced relationship from said target tracking system (20, 30); a first wandering light point being projected onto said projection well (24) by a target point light source (12) so as to represent a simulated target, said scanner device (30) including a second light source (18) projecting a second light point onto said projection wall (24) for following of sad first wandering light point to provide a control over the scanner device (30) actually detecting the wandering target simulating light point, and means (20,14) for computing the alignment of said first and second light points on said projection wall, whereby said second light point being located more closely to the target-simulating light point is indicative of said scanner device (30) being more precise in tracking the movement of said wandering target-simulating light point.
