Laser tracking system (LTS) is one of the most powerful measurement and tracking instruments, and it has been widely used in accurate target tracking and measurement process in commercial or military applications in recent years. However traditionally, most approaches on the LTS provided very little detailed and complete information on building, developing, testing and troubleshooting processes for the LTS. To fill this gap, this book provides very detailed descriptions and analyses, both theoretically and practically, on optical, echanical, electronic and computer control programs in how to build and implement a real LTS with a complete set of documents. Some novel approaches, such as self-calibration of tracking gimbals and fuzzy logic control, are also covered in the book. A technical manual that provides detailed practical designs and considerations is also included. With the help of this book, a college student, researcher and engineer can build a real LTS more easily and conveniently.
