Abstract
The fiber optic pressure sensing system includes a sensor housing formed using MEMS processing. The sensor housing has ribs and grooves in both horizontal and vertical directions relative to the surface to allow the membrane to flex in a consistent manner. The flexing of the membrane allows the pedestal to be repeatedly positioned in response to pressure acting on the extension of the sensor head and membrane.
Claims10
An optical connecting system comprising:
- a housing having a central axis;
- a first optical fiber coupled to the housing having a first end;
- a second optical fiber coupled to the housing along the central axis having a second end;
- a lens;
- and
- a lens scanning device movably coupling the lens within the housing along the central axis, said lens scanning device moving the lens relative to the housing to direct light from the first end to the second end, said lens scanning device comprising,
- a lens holder coupled to the lens,
- a first motion arm coupled to the lens holder,
- first controllable means coupled to the first motion arm to generate a first motion on the lens holder though the first motion arm,
- a second motion arm coupled to the lens holder, and
- a second controllable means coupled to the second motion arm to generate a second motion on the lens holder through the second motion arm.
