Paper Abstract

The consistency of optical-axis between aiming and transmitting of continuous vari-focus laser communicating system is the important factor influencing the effective distance of communication. Therefore, the research for the consistency of optical-axis is very important. Based on the analysis of the defects of the present testing method which examine the deviating extent of the aiming light spot from the reticle by eye observation, The paper provides a new testing method for the continuous vari-focus communicating system such as the application of advanced image-sampling technique by CCD and image-processing technique by computer, especially close-cycle adaptive controlled image-processing technique. Meanwhile, the paper designs a advanced automatic testing equipment. The result of experiment proves the feasibility of the project and shows the broad applying prospects.
