Optical techniques have always been used for a large number of automotive, metrological and sensing applications. Fiber- and integrated- optics technologies were primarily developed for telecommunication applications. However, the advances in the development of high quality and competitive price opto-electronic components and fibers have largely contributed to the expansion of guided wave technology for sensing as well. What is Opto-Electronics?

Pitch – The physical quality of sound that relates to the frequency of the wave. Radial Force Variation (RFV) – A measurement of the tire’s uniformity, under load, in regards to the variation of the load acting towards the center of the tire; commonly referred to as the tire’s sidewall variation. Radial Run out – A condition where a rotating

Audible Range of Sound – Sounds that are in the range of 20 to 20,000 Hertz (Hz). Amplitude – The vertical measurement between the top and bottom of a wave. Also see magnitude. Beat – An NVH concern produced by two sounds that is most noticeable when the frequency difference is 1 to 6 Hz. Bead Seating – The process
