About

Dr. Thomas O. H. Charrett is a leading researcher in optical metrology and robotic manufacturing, specializing in non-contact sensing techniques that enhance precision in autonomous and industrial systems. His major contributions center on laser speckle velocimetry and sensor development for robotic applications, including tool speed measurement, odometry for autonomous vehicles, and error compensation in additive manufacturing. His most-cited work, "A non-contact laser speckle sensor for the measurement of robotic tool speed" (25 citations), demonstrates a cost-effective method for real-time speed monitoring. His 2012 study on objective speckle velocimetry for autonomous vehicle odometry (19 citations) pioneered translation measurement through speckle pattern correlation, offering a robust alternative to traditional odometry. Charrett also developed the workpiece positioning sensor (wPOS), a three-degree-of-freedom optical sensor for robotic end-effector positioning, and advanced absolute angle measurement using dual-wavelength laser speckle. His work addresses critical challenges in robotic manufacturing, such as motion errors and flexibility limitations of CNC systems, with notable achievements in low-cost, non-contact sensing solutions. With a focus on practical, scalable technologies, Charrett’s research has significant implications for autonomous robotics and industrial automation, as evidenced by his growing citation impact.
