Studying on the critical technology of 4×1 Collimation light arrays

The collimated light source is used to demarcate other optical components.Therefore,it is more important to confirm the orientation of the parallel light beam.Because manufacturing and installation factors cause initial position uncertainty of optical axis of collimation light,the oriental position of collimated light need adjustment.It presents four-freedom mechanisms to realize adjustment of the optical axes location of collimated light and analyze function and structure of the four-freedom adjusted mechanisms.The mathematical model of four-freedom adjusted mechanism which has been built is applied to realize the optical axes location adjustment of the collimated light,and use the model quantized the adjusted quantity during the Optical axes location of the collimated light.
