    摘要: A range discriminating optical sensor for use in a vehicle safety system is provided. The range discriminating sensor is designed to create a small depth of field such that objects at a range outside of the depth of field are eliminated from the image. Generally, the optical sensor uses a large aperture to limit the depth of field. An electronic imaging element is used to detect the image projected by the lens. The electronic imaging element may have a small pixel size which further reduces the depth of field. A signal processor can be used to determine the distance from the image sensor with objects with the selected depth of field appearing in focus and those outside of the depth of field appearing out of focus.

    摘要: A misalignment detection sensor assembly is provided, which includes a forward-looking sensor having a sensing direction along a first axis and an inertia sensor configured to sense acceleration along a second axis, the second axis having a fixed relationship with respect to the first axis. A misalignment detection system uses the misalignment detection sensor assembly and a signal processing system to calculate a misalignment angle between the first axis and the direction of forward motion of the sensor assembly. A method of detecting angular misalignment of a forward-looking sensor assembly is also disclosed, which includes measuring acceleration along an axis having a fixed relationship with respect to the sensing axis of the forward-looking sensor assembly and comparing the acceleration measurement with a predetermined threshold.
