Guidance Information

Laser beam riding guidance was a new concept of guidance technology put forward in 1970s. It is widely used in various laser guided weapon systems. The technology of generating information field in the laser beam riding guidance system is the key of the system. However, the traditional laser beam riding guidance technology needs complex mechanical devices for the generation of guidance information field, optical zoom control and so on. There are many problems, such as the complex structure and it is difficult to guarantee the precision. In this paper, Optical Phased Array (OPA) is used to explore a new method of generating laser beam riding information field, which can realize the non-inertia and rapid deflection control of the beam.

Optical Measurement Method

A new in-process optical measurement method has been developed for measuring surface profiles of workpieces under the coolant condition. In this method, a laser beam passes through two additional layers. This paper presents an error analysis for the new method. The effects of key parameters on performance of the new method are examined. The theoretical analysis and experimental results show that the measurement error in this new method can be controlled within an acceptable range.
