摘要 |
A fiber optical displacement sensor having a wider range of measurable distances and displacements. The fiber optical displacement sensor includes collimation device, attached to ends of projecting and receiving optical fibers, for collimating a projection beam to be emitted from an end of the projecting optical fiber facing toward a surface to be measured and a reflected beam to be received by an end of the receiving optical fiber facing toward the surface to be measured.
