Abstract
An optical device may include a tubular body defining a field-of-view (FOV). A first slew ring bearing may be carried by the tubular body. A second slew ring bearing may be carried by the first slew ring bearing. An occulter arm may be selectively movable by the first and second slew ring bearings for occluding a selected portion of the FOV.
Claims20
An optical device comprising:
- a tubular body defining a field-of-view (FOV);
- a first slew ring bearing carried by the tubular body;
- a second slew ring bearing carried by the first slew ring bearing;
- and
- an occulter arm selectively movable by the first and second slew ring bearings for occluding a selected portion of the FOV.
2 more elements
An optical device comprising:
- a tubular body defining a field-of-view (FOV);
- a first slew ring bearing carried by the tubular body;
- a second slew ring bearing carried by the first slew ring;
- a first drive associated with the first slew ring bearing;
- a second drive associated with the second slew ring bearing;
- an occulter arm coupled to the first and second slew ring bearings;
- and
- a controller coupled to the first and second drives to selectively move the occulter arm for occluding a selected portion of the FOV.
5 more elements
A method for occluding a selected portion of a field-of-view (FOV) defined by a tubular body of an optical device, the method comprising:
- operating a first slew ring bearing carried by the tubular body;
- and
- operating a second slew ring bearing carried by the first slew ring bearing so that an occulter arm operatively coupled to the first and second slew ring bearings is selectively moved for occluding the selected portion of the FOV.
