Abstract
Abstract Described is a testing system which has a target point light source ( 12 ), a tracking light source ( 18 ) and therebetween a projection wall ( 24 ). Associated with the target point light source ( 12 ) is a two-axis deflection device ( 28 ) which is connected together with a target point computer ( 14 ). Associated with the tracking light source ( 18 ) is a two-axis scanner device ( 30 ) which is connected together with a tracking computer ( 20 ). Provided between the tracking light source ( 18 ) and the two-axis scanner device ( 30 ) is a beam splitter ( 32 ) with which a sensor device ( 42 ) is associated.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
188 words
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.
Claim 2
Dependent Claim
188 words
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.
Claim 3
Dependent Claim
60 words
A test installation according to claim 1 , wherein said target point light source ( 12 ) has a two-axis deflection device ( 28 ) operatively associated therewith for projecting said target-simulating wandering light point onto said projection wall ( 24 ); and a target point computer ( 14 ) being connected to said two-axis deflection device ( 28 ).
Claim 4
Dependent Claim
78 words
A test installation according to claim 1 , wherein said second light source ( 18 ) comprises a tracking light source arranged on an optical axis of the tracking system, said scanner device comprising a two-axis scanner device; a beam splitter ( 32 ) being arranged between said tracking light source ( 18 ) and said two-axis scanner device ( 30 ); and a sensor ( 42 ) being operatively associated with said beam splitter ( 32 ).
Claim 5
Dependent Claim
22 words
A test installation according to claim 1 , wherein said target point light source ( 12 ) comprises a target point laser.
Claim 6
Dependent Claim
20 words
A test installation according to claim 1 , wherein said second light source ( 18 ) comprises a tracking laser.
Claim 7
Dependent Claim
30 words
A test installation according to claim 3 , wherein a color filter ( 44 ) is arranged between said sensor ( 42 ) and said beam splitter ( 32 ).
Claim 8
Dependent Claim
24 words
A test installation according to claim 1 , wherein said projection wall ( 24 ) comprises a light-transmissive ground glass screen ( 26 ).
Claim 9
Dependent Claim
20 words
A test installation according to claim 1 , wherein said projection wall ( 24 ) comprises a diffusely light-reflecting material.
