Two-dimensional calibrating standard. Physicist holding an X-Y (two-dimensional) optical position standard. The X-Y standard is made from glass or quartz and has a reflective chromium-coated pattern of many crosshairs spanning its surface. These crosshairs are designed to calibrate measuring machines that use a viewing system to locate features. Such machines are used in the automated optical inspection (AOI) of circuit boards,where a camera autonomously scans the boards for faults such as missing components.
