Abstract

An illustrative example embodiment of a detector device, which may be useful on an automated vehicle, includes a multiple-dimensional array of detectors including a plurality of first detectors aligned with each other in a first direction and a plurality of second detectors aligned with each other in the first direction. The second detectors are offset relative to the first detectors in a second direction that is different than the first direction. A processor determines an interpolation coefficient related to the offset between the first and second detectors and determines an angle of detection of the device based on the interpolation coefficient.
