Scan Management is handled by the Scan Manager control or by the Scan settings group in the Basic Mode Main Controls window.
Scan Types
Linear
A linear scan is a simple 2-axis scan where one axis moves along a scan line, and the other steps a small amount each line, thus creating a rectangular raster scan image. A linear scan works with any two pairs of axes in a system (including Turntables/Rotators).
Linear MultiStep (ODIS-NDT only)
A linear MultiStep scan is where a scan axis moves in a linear path, but multiple axes may be involved in the step motion. For example, scanning up a wedge shape involves a single scan axis (X) but multiple step axes (Y and Z).
The path for the step motion can be defined either with a contour or defining the shape of the part using the "Define Part" option.
Linear Surface (ODIS-NDT only)
A linear surface scan is used when both the Scan and Step motion involve multiple axes, e.g. scanning an asymmetrical surface such as a fan blade. A surface must be defined using Teach-and-Learn or other methods.
Tray
A tray scan is a type of scan where multiple parts are arranged in a regular grid. The tray scan can skip the regions between parts when scanning. Commonly used for scanning JEDEC trays of parts.
Rotational (ODIS-NDT only)
If a Turntable or Rotator is present in the system, a Rotational scan can be performed where the turntable/rotator moves constantly, while a step axis increments every rotation.
Rotational MultiStep (ODIS-NDT only)
A rotational multistep scan performs a constant rotation on a turntable/rotator, with a step motion that involves multiple axes. For example, scanning a nose cone may involve Y, Z and Gimbal motion.
