Abstract

A method and system for three-dimensional imaging of objects, including integrated circuit interconnections to improve the efficiency of triangulation-based laser line scanning systems. A scanning beam is incident at a normal angle to the X,Y inspection plane with the scan line oriented at 45.degree., diagonal to an axis defining a first direction of motion. Motion of the imaging head along the axis is used to acquire line scan images in the non-orthogonal coordinate system.
