Observer systems and methods
View Patent ↗An observer system includes a support frame, a first support member, a second support member, and an observer. The first support member is attached to the support frame such that the first support member is rotatable relative to the support frame about a first axis. The second support member is attached to the first support member and extends along a second axis, and an observer is attached to the second support member such that the observer is able to rotate about the second axis. The observer is rotatable relative to the support frame about both the first and second axes such that the observer can achieve a 4 pi steradian field of regard.
1 . An observer system, comprising:
a support frame;
a first support member attached to a first face of the support frame, wherein the first support member is rotatable about a first axis that is substantially perpendicular to the first face;
a second support member attached to the first support member, wherein the second support member extends along a second axis; and
an observer attached to the second support member such that the observer is able to rotate about the second axis and substantially parallel to the first axis;
wherein the observer is rotatable relative to the support frame about both the first axis and the second axis such that the observer has a 4 pi steradian field of regard.
2 . The observer system according to claim 1 , further comprising a third support member that is rotatable attached to the second support member and fixed to the observer, wherein the third support member allows the observer to rotate about the second axis.
3 . The observer system according to claim 1 , wherein the first axis is perpendicular to the second axis.
4 . The observer system according to claim 1 , wherein the observer is offset from the first face of the support frame such that the observer does not contact the support frame as the observer rotates about the first axis and the second axis.
5 . The observer system according to claim 1 , wherein the observer has a 4 pi steradian field of regard when the support frame is in any arbitrary position.
6 . The observer system according to claim 1 , wherein the observer comprises an optical sensor.
7 . The observer system according to claim 1 , wherein the first face of the support frame comprises an upper rectangular shaped portion and a bottom rounded portion.
8 . The observer system according to claim 1 , further comprising a rotary fiber optic cable that is attached to the observer for transmitting data from the observer, wherein the rotary fiber optic cable has a first rounded portion that is concentric with the first axis when in a folded configuration and a second rounded portion that is concentric with the second axis when in a folded configuration.
