20.6.2 POF Sensors
Fiber optic sensors using POF have been described in a general overview [52,
53]. POF sensors are mostly restricted to multimode fibers, are of intrinsic and
extrinsic type, and the change of intensity will be measured in most cases.
In these application areas, additional benefits of POFs are exploited such as
ease of handling, robustness, flexibility, and low weight. These new systems
benefit from the positive experience gained with more than 4 million cars
equipped with optical data bus systems using MOST, D2B, or Byteflight. One
possible sensor is the Pedestrian Protection System (PPS), developed and pub-
lished by Siemens VDO
