Abstract
Abstract An observation and guide beam apparatus, referred to as a spotter scope, has in addition to a laser guide beam generator an optical daytime channel for daytime spotting or viewing and a day- and nighttime channel for both night and day observations. These channels are harmonized relative to the laser guide beam by the same automatic axial harmonizing device. Further, the day and night channel includes a heat imaging device that is internally harmonized on a long term basis. The scope also has an ocular arm. This combination is especially suitable for use in a weapons system using remote controlled flying bodies, for example. The scope can use any available type of detector or detector technology.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
199 words
An observation and guide apparatus comprising a first viewing system (10) including first means suitable for night viewing or day viewing, said first means including a channel (10b) having a first optical axis (10a), said apparatus further comprising second means (13) forming a daylight channel (13b) having a second optical axis (13a), said first and second optical axes (10a and 13a) being harmonized with each other on a long term basis, a guide beam projector (12) for generating a guide beam defining a third optical axis (12a), an ocular arm (14) optically connected to both said first and second means, and axial harmonizing means (11) provided for automatically harmonizing said first and second optical axes (10a and 13a) with said third optical axis of said guide beam projector (12), said apparatus further comprising means for statically and mechanically fixing said first and second optical axes (10a and 13a) in a rigid position, said harmonizing means including adjusting means (11a) arranged in said second optical axis (13a) of said daylight channel (13b) for enforcing a parallelism between said first and second optical axes (10a and 13a), such that the apparatus is especially useful for weapons systems using remote controlled weapons.
Claim 2
Dependent Claim
199 words
An observation and guide apparatus comprising a first viewing system (10) including first means suitable for night viewing or day viewing, said first means including a channel (10b) having a first optical axis (10a), said apparatus further comprising second means (13) forming a daylight channel (13b) having a second optical axis (13a), said first and second optical axes (10a and 13a) being harmonized with each other on a long term basis, a guide beam projector (12) for generating a guide beam defining a third optical axis (12a), an ocular arm (14) optically connected to both said first and second means, and axial harmonizing means (11) provided for automatically harmonizing said first and second optical axes (10a and 13a) with said third optical axis of said guide beam projector (12), said apparatus further comprising means for statically and mechanically fixing said first and second optical axes (10a and 13a) in a rigid position, said harmonizing means including adjusting means (11a) arranged in said second optical axis (13a) of said daylight channel (13b) for enforcing a parallelism between said first and second optical axes (10a and 13a), such that the apparatus is especially useful for weapons systems using remote controlled weapons.
