Laser structured-light sensors have been widely used in industrial robots for various applications like on-line programming, parts measurement and quality control, parts identification and localization, etc. In this chapter we address some fundamental aspects of the laser structured-light sensor. We first present how a laser structured light sensor is formed. It is followed by a discussion on limitations of accuracy and the effect of laser speckle and environmental factors concerning measurement accuracy. Finally, we list the commercially available laser structured-light systems.
