A system and method for achieving constant magnification of a scanned three-dimensional item without the use of special optics or other specialized hardware. The system includes the dynamic computation of a camera parameter-dependent factor and applying that factor in real-time to the sampled signal resulting from the scan of the item.

Constant magnification imaging method and system

Systems and method for determining, based on a gray scale image, focus of an imaging system. A method of this invention includes the steps of: a) acquiring a gray scale image of a test target, b) binarizing the acquired gray scale image, c) analyzing the binarized acquired image, d) adjusting focus of acquisition optics of the imaging system, and e) repeating steps a) through d) until a substantially maximum number of line pairs of a number of groups of line pairs of the test target is obtained, wherein each group from the number of groups of line pairs has a predetermined spatial frequency.

Methods and systems for evaluating optical systems

A system and method for collecting relatively high resolution amplitude data with a conventional sensing device from a signal source that is sampled at a relatively low characteristic scan resolution, and then generating relatively high scan resolution, relatively low resolution amplitude data through real-time application of up-sampling and quantization algorithms. The resulting relatively high scan resolution, relatively low resolution amplitude data closely approximate the image quality resulting from a sensing device operating at a much higher scan resolution, using a conventional data collection system. The invention relates generally to systems that collect the high resolution amplitude data that must be converted to low resolution amplitude data in order to maximize throughput rates.
