In order to prove the feasibility of using fiber to transmit light and using self-focus lens to collect feedback light,the collection efficiency model of self-focus lens was built,and then much attention was put on how the collection efficiency of the self-focus lenschanges with radius and working distance.The feasibility of using fiber to transmit light and using self-focus lens to collect feedback light is theoretically proved.Finally,the experimental facility was established,the experiments were carried out.The experimental results show that this new instrument can acquire fine signal at long working distance with little disturbance induced by environment.
