Abstract: A machine vision system images bar code labels moving through a horizontal plane at variable object distances within the system's object depth of field Zobj with a plurality of sequential line images, each with different object lengths which gradate Zobj into plural focused object planes, and the object plane within which the bar code label lies provides a focused optical image of the bar code to a multilinear photodetector which transduces the focused optical image into a corresponding electrical siganal for further processing.

Abstract: A geometric sensor includes a Monolithic Lenslet Module (MLM) subaperture array (22) having a plurality of microlenses (40), each of which have an opaque center marking formed concentric with the micolens optical axis (44), at the location of the lens chief ray, to produce an integral geometric reference (IGR) spot pattern of the lens array which is used to correct for sensor errors to an accuracy comparable with that achieved with reference plane wave calibration.
