Patent Images

1. An imaging device comprising:

  • a plurality of linear imaging arrays and image formation optics that provide field of views corresponding to the plurality of linear imaging arrays;

    at least one illumination module that produces planar light illumination that overlaps the field of views corresponding to the plurality of linear imaging arrays; and

    image processing circuitry that analyzes pixel data values of a plurality of composite 2-D images, wherein each composite 2-D image is derived from sequential image capture operations of one corresponding linear imaging array so as to derive velocity data that represents an estimated velocity of said imaging device with respect to at least one target object disposed in said field of views.
