1. 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.

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.
