Abstract
A laser inspection tool system (100) includes a hand-held remote tool head (108) that provides an image of a target object (116) and a measurement surface (118). The remote tool head (108) includes light sources (208) and mirrors (210) that in conjunction generate two perpendicular lines of light that impinge the target object (116) and the measurement surface (118) and reflect to a form an image in a camera (218) in the remote tool head (108). The remote tool head (108) may be oriented at any angle relative to the measurement surface (118). A processor (102) remotely coupled to the remote tool head (108) captures the image and determines the offset between the light reflected by the target object (116) and the light reflected by the measurement surface (118), and the angle between the reflected lines of light. Using the offset and the angle, the processor (102) determines the height of the top of the target object (116) above the measurement surface (118) and the angle of the remote tool head (108) relative to the measurement surface (118).
