Abstract
An inspection system for irregular objects such as solder joints wherein the system utilizes first and second sensors adapted to be pivotable about a common pivot axis and such that the projection axes of the sensors and the pivot axes are able to intersect at a common.
Claims30
An apparatus for inspecting objects comprising:
- first sensor means for projecting electromagnetic radiation along a first projection axis and viewing reflected radiation along a first viewing axis;
- second sensor means for projecting electromagnetic radiation along a second projection axis and viewing reflected radiation along a second viewing axis;
- said first and second sensor means being adapted to be independently pivotable about a first common pivot axis and being further adapted such that said first and second projection axes and said first and second viewing axes intersect said first common pivot axis at substantially a common point.
A method for use in inspecting objects comprising:
- projecting electromagnetic radiation along a first projection axis and viewing reflected radiation along a first viewing axis with a first sensor means;
- projecting electromagnetic radiation along a second projection axis and viewing reflected radiation along a second viewing axis with a second sensor means;
- independently pivoting said first and second sensor means about a first common pivot axis;
- and said first and second projection axes and said first and second viewing axes intersecting with said first common pivot axis at substantially a common point.
