This target’s dimensions are 7″ x 10″ x 1/8″ (17.8 x 25.4 x 0.32 cm). It is a companion to the object-level target. It is designed to allow scanner performance measurements over a larger field of view. In addition to enabling the same ISO metrics as the object-level target, it can provide for measuring illumination uniformity, spatial distortion, and resolution variability over the target’s areal coverage. This target is best suited for scanner benchmarking or session-to-session quality control and is compatible with Image Science Associates GoldenThread software.
