Security inspection equipment three-dimensional linear resolution test body and method

The invention provides a three-dimensional linear resolution test body and method for security inspection equipment, belongs to the technical field of security inspection equipment testing, and is mainly used for testing the three-dimensional image quality of the security inspection equipment. The three-dimensional linear resolution testing body of the security inspection equipment comprises a testing body, the testing body comprises a cylindrical substrate, a plurality of line-shaped grooves are engraved in the surface of the cylindrical substrate, and the line-shaped grooves are evenly arranged in the surface of the cylindrical substrate in the length direction of the cylindrical substrate. And a copper wire with a corresponding outer diameter is arranged in each line-shaped groove. Wherein the cylindrical base is made of a plastic material. Wherein the line diameters of all the line-shaped grooves are different from one another. The test body can be used for testing the resolution capability of the securit
