Checkerboard Charts for Imatest LED Light Sources
The Checkerboard Test Charts are available Pre-Mounted for use with Imatest LED Light Sources. This chart is designed to work with the Checkerboard module. This module enhances testing of varying distances by supplying more testable regions to provide automated measurements of sharpness, lateral chromatic aberration, and distortion from images.
Learn more about the Checkerboard Module. Please note that this module runs slower than eSFR ISO and SFRplus modules and is less tolerant to extreme amounts of defocus or blooming degradations.
Description
The Checkerboard Test Chart is available on different materials for Visible Spectrum or Near Infrared (NIR) testing. For the Visible Spectrum choose between: Inkjet, High Precision Color Film, or High Precision Black and White Film. For the Near Infrared (NIR) Spectrum, choose between: Inkjet or High Precision Black and White Film. Contrast ratios include 4:1 or 10:1. All options are printed with 12 vertical squares.
For systems greater than 25MP, please consider our Chrome on Glass Checkerboard Targets.

Documentation and software support
Checkerboard can be run either through the highly-interactive Rescharts interface or as a batch-capable fixed module. The key documentation for getting started is Using Checkerboard Part 1, found in the Checkerboard section of the Documentation page. Checkerboard provides the most accurate distortion measurements.
