Shock detection optical fiber sensor

A shock detection optical fiber sensor, comprising:

• a plastic optical fiber;
• a corrugated plate comprising a plurality of protrusions arranged in the longitudinal direction of the plastic optical fiber, and formed opposite the plastic optical fiber;
• a mold plate covering the plastic optical fiber and the corrugated plate;
• a light emitting element connected to one end of the plastic optical fiber;
• and
• a light receiving element connected to the other end of the plastic optical fiber,
• wherein the plurality of protrusions comprise a substantially trapezoidal protrusion comprising a planar portion formed opposite the plastic optical fiber.
