Abstract

A method of making a fiber optic accelerometer includes (a) drawing an optical fiber through a resin; (b) winding the resin coated fiber onto a disc mounted on an assembly having a central shaft; and (c) curing the resin-coated fiber. The optical fiber may be drawn through a resin by providing a container filled with a resin having an orifice therethrough and drawing the fiber through the orifice. The resin may be cured such that the fiber is bonded to the disc by curing the resin to the fiber and the disc at the same time.

Claims

1. A method of making a fiber optic accelerometer, comprising:

a) drawing an optical fiber through a resin;

b) winding said resin coated fiber onto a disc mounted on an assembly having a central shaft such that inter-space of the wound fiber is filled with resin;

c) curing said resin-coated fiber, such that the fiber bonds to the disc during curing; and

d) wherein said disc is rotated during said curing.

2. The method of claim 1, further comprising wiping excess resin from said fiber.

3. The method of claim 1, further comprising providing a gap between said central shaft and said resin coated fiber.

4. The method of claim 1, wherein drawing an optical fiber through a resin includes providing a container filled with a resin having an orifice therethrough and drawing said fiber through said orifice.
