A sensor system for a structure includes at least one laser diode or LED light source coupled to a bundle of optical fibers, optical sensors integral with the structure and coupled to optical fibers wherein the sensors are adapted for modulating the intensity, frequency and phase of the optical signals in response to strain, temperature, pressure or another stimulus, a CCD video camera for collecting the modulated optical signals from optical fibers which are formed into a bundle representing a distinct structural area, and either a video monitor for visually evaluating the sensor data or a digital computer for image processing of the data.
