Disclosed are displacement sensors constructed from optical fibers having a long elongation with low-cost ToF sensors that advantageously do not suffer the infirmities of the art. The ToF sensor and the optical fiber ends that launch and receive light are packaged such that no ambient light affects measurements, and the structure is protected from contamination which eliminates optical degradation. With multi-point measurement capabilities and the low-cost features of ToF sensors, many displacement sensors can be arranged in a mesh to map out displacements over a large area and over all directions for civil and/or geotechnical structures. Wireless or other communications mechanisms may be employed in conjunction with our novel sensors to send real time measurement data to a central office for real time monitoring and analysis.
