Abstract: A process comprises projecting a radiation beam (213) from a movable optical element (202) onto an image sensor positioned along an optical axis (210) of the movable optical element (202) and substantially normal thereto. The movable optical element (202) is movable relative to the image sensor (222) and the radiation beam is projected at a selected angle relative to the optical axis. A plurality of targets are positioned at known front focus distances from the movable optical element, and for each front focus distance, a back focal length of the movable optical element and the position where the beam of radiation falls on the image sensor are recorded.

Abstract: According to embodiments of the present invention, a barcode scanner platform is provided in which the gain of an analog signal representative of a barcode is controlled using a control loop. In embodiments, an MTF detector generates a value (e.g., DC) representative of a low frequency portion (wide or out of optical focus elements) of the analog signal and a second value (e.g., DC) representative of a high frequency portion (narrow elements or in optical focus elements) of the analog signal. The processor uses the first and the second values and a reference amplitude to determine a gain signal. The processor provides the gain signal to an AGC circuit that provides a linear response to the gain signal using matched JFETs. A noise filter can be enabled or disabled based on the first value, the second value, and/or the barcode scanner platform read rate.

Abstract: Embodiments of a method, apparatus, and article of manufacture for rapidly capturing images in an automated identification system to effectively extend one dimension of a field of view of an image system are disclosed herein. In one embodiment, the image system captures and processes multiple images of at least a portion of a surface of a component in the automated identification system in response to a trigger signal communicated from a triggering device configured to sense a location of the component. Various embodiments of the invention include multiple sources for capturing images, and/or multiple user-specified schemas for effectively extending the field of view of the image system along the axis of component travel in the automated identification system.
