ABSTRACT:
A system of partially transparent light beam detectors that allow passage of the light beam through the detector allows multiple detectors that use the same reference light beam. Transparent detectors can be position sensitive detectors (PSD), photodiode arrays, or CCD imaging arrays. The detectors are attached to vibration susceptible structural elements, with detected movement of the light beam with respect to the partially transparent light beam detectors corresponding to movement of the vibration susceptible structural element.
