Design of parallelism measuring equipment for laser beams from independent laser expanding beam system

To accurately measure the transmission directions of high power laser beams from a laser independent expanding beam system in the laser launching system,the equipment for measuring the parallelism error of independent expanding beam system is designed.Firstly,based on the speciality of the independent expanding beam system and the IR laser,the equipment uses a high resolution IR CCD for measuring and imaging.Then,the mechanical structure of the equipment is constructed by using aluminum alloys with light quality and high rigidity,and its activity parts are building on a linear moving platform with high precision.On the basis of the high resolution CCD and the precise displacement platform,the equipment can implement the dynamic and static measurement.The experimental results show that the equipment works stably and reliably and measuring precision is better than 2″.It satisfies the requirements of the laser launching system,and can provide basis for the assembly and application of the expanding beam systems.
