Abstract
Abstract A device for guiding by night self-propelled missiles, comprising a daylight sighting telescope and an infrared goniometer which in association are called here daylight localizing apparatus, for spotting an infrared source carried by the missile, and a thermal telescope for night vision, to which are associated an infrared detector and a display member, further comprising a thermal reticle, optical means for forming outside the daylight localizing apparatus the image of the daylight telescope reticle, means for shifting the daylight telescope reticle image so that it coincides with the thermal reticle, optical means for forming the thermal reticle image on the thermal telescope detector, and an adequate frame mechanically attached to the daylight localizing apparatus for supporting said means, said thermal reticle, the thermal telescope and its associated detector and display member.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
114 words
A device for tracking by night self-propelled missiles, comprising a daylight sighting telescope provided with an optical reticle, an eyepiece and an infrared goniometer which in association are called here daylight localizing apparatus, for tracking an infrared source carried by the missile, and a thermal telescope for night vision, to which are associated an infrared detector and a display member, further comprising a thermal reticle, optical means for providing an optical path between said eyepiece and said thermal reticle to enable viewing of the thermal reticle image in said daylight telescope, and adjusting means for bringing into coincidence the image of the optical reticle of the daylight telescope with that of the thermal reticle.
Claim 2
Independent Claim
114 words
A device for tracking by night self-propelled missiles, comprising a daylight sighting telescope provided with an optical reticle, an eyepiece and an infrared goniometer which in association are called here daylight localizing apparatus, for tracking an infrared source carried by the missile, and a thermal telescope for night vision, to which are associated an infrared detector and a display member, further comprising a thermal reticle, optical means for providing an optical path between said eyepiece and said thermal reticle to enable viewing of the thermal reticle image in said daylight telescope, and adjusting means for bringing into coincidence the image of the optical reticle of the daylight telescope with that of the thermal reticle.
Claim 3
Dependent Claim
23 words
A device according to claim 1, wherein the optical means comprises a dichroic plate, a roof prism, a separating prism and a lens.
Claim 4
Dependent Claim
23 words
A device according to claim 2, wherein the adjusting means comprises means for shifting the lens and means for rotating the thermal reticle.
Claim 5
Dependent Claim
32 words
A device according to claim 1, wherein the means for forming the image of the thermal reticle on the thermal telescope detector comprise deflecting mirrors, an infrared lens and a reflecting prism.
Claim 6
Dependent Claim
15 words
A device according to claim 1, wherein the display member comprises its own observation eyepiece.
Claim 7
Dependent Claim
30 words
A device according to claim 1, wherein optical means are further provided which are arranged for the observer's eye to see the display member through the daylight sighting telescope eyepiece.
Claim 8
Dependent Claim
31 words
A device according to claim 6, wherein said means for seeing the display member through the daylight telescope eyepiece comprise a separating prism inserted between the roof prism and the lens.
Claim 9
Dependent Claim
33 words
A device according to claim 1, comprising a frame attached to the daylight localizing apparatus for supporting said adjusting means, said thermal reticle, said thermal telescope and its associated detector and display member.
