Patent ID: 8155486

Claim:
A fiber optic sensor comprising: first and second flexural discs that are spaced apart from one another along a central axis; a fiber optic coil affixed to one of said first and second flexural discs; a proof mass disposed between said first and second flexural discs; a first stop member, disposed between said proof mass and said first flexural disc, said first stop member sized to i) provide space between said proof mass and said first flexural disc to allow for normal motion of the first flexural disc, and ii) interfere with movement of said first flexural disc to prohibit unwanted extreme motion of said first flexural disc; and a second stop member, disposed between said proof mass and said second flexural disc, said second stop member sized to i) provide space between said proof mass and said second flexural disc to allow for normal motion of the second flexural disc, and ii) interfere with movement of said second flexural disc to prohibit unwanted extreme motion of said second flexural disc; and wherein said fiber optic sensor includes only a single fiber optic coil.
