Abstract: A proactive vehicular security system is provided. The proactive vehicular security system embodies a new use for lidar radar providing a lidar radar system operatively associated with a vehicle, the lidar radar system configured to provide a field of view defining a coordinate system adjacent to the vehicle so that each separate object in the field of view can be defined by the coordinate system; the lidar radar system configured to provide a zonal coordinate system for a structural profile of the vehicle wherein a datum of the zonal coordinate system comprises a datum for each zone of a plurality of zones comprising the zonal coordinate system, and wherein changes in the zonal coordinates associated with the structural profile, relative to the datum of the zonal coordinate system, indicates metes and bounds of damage to or additions to the structural profile of the vehicle.

Abstract: The present invention provides a method and apparatus for compensating for the age induced wavelength drift in a tunable DBR. In practice, the tuning characteristic (i.e. output wavelength versus tuning current) of a tunable DBR may be characterized before and after factory aging, typically in the form of a burn-in or purge cycle. An aging vector may be constructed in accordance with the ratio of the change in the tuning characteristic associated with a second output wavelength and the change in the tuning characteristic associated with a first output wavelength as a function of the factory aging. In addition, the tuning characteristic associated with transmission at the first output wavelength may be monitored in the field.
