Abstract
A method for determining the surface quality of an object includes the steps of providing an object having a surface and projecting a series of spaced parallel lines onto the surface of the object from a first axis. The pattern formed by the lines on the object surface is viewed and any non-uniformlty of the object's surface is ascertained by observing a variation of the line spacing on the object's surface.
