We also offer several versions of high-contrast positive reflective targets. For more information on each pattern, see the Resolution Targets tab.Īll of our resolution test target patterns are available as positive targets, and many have negative versions as well. Targets are also available with sector star (also known as Siemens star) patterns, Ronchi rulings, a variable line grating, or a combination of patterns for resolution and distortion testing. Thorlabs offers resolution test targets with 1951 USAF, NBS 1952, and NBS 1963A patterns. By identifying the largest set of non-distinguishable lines, one determines the resolving power of a given system. They consist of reference line patterns with well-defined thicknesses and spacings and are designed to be placed in the same plane as the object being imaged. Resolution test targets are typically used to measure the resolution of an imaging system.

Glue the grid to the cereal box so the checkboard is more rigid.Or, you can draw your own grid on white cardstock using a marker and ruler.You can print out the checkerboard pattern and color alternating squares with markers or crayons.Paint the checkers with markers or acrylic paints.When they are dry, you can sand any uneven edges, if desired.Carefully turn them over from time to time to encourage even drying. After the checkers are formed, set them aside to dry.The grid pattern includes a size guide for the included checkerboard grid. Or, you can form a small ball of clay and flatten it with your thumb.You can use a small round cookie or canape cutter. Might want to make a couple of extras just in case one gets lost! There are two ways to form the checkers. You’ll need 24 checkers total of -12 of each color.Roll over the clay and flatten it until the rolling pin touches the skewers. You can get an even thickness by placing a skewer at each side of the clay. ![]()
