Abstract
A system may monitor a vibration isolating connection between a first part and a second part. The system may include a light source, an optical sensor mounted to receive light from the light source, and a processing unit for providing an output indicative of the deformation of the vibration isolating connection based on the output of the optical sensor.
Claims23
A system for monitoring a vibration isolating connection between a first part and a second part, the system comprising:
- a light source configured to generate light based upon a plurality of different modulation frequencies, and interleave the plurality of different modulation frequencies;
- a single photon avalanche diode (SPAD) optical sensor configured to receive the light from said light source;
- and
- a processor configured to provide an output indicative of deformation of the vibration isolating connection based upon an output of said SPAD optical sensor and the plurality of different modulation frequencies.
