本文通过对目前自聚焦透镜光学参数测量方法的分析,提出了能同时测量自聚焦透镜轴心折射率n_0和聚焦常数(二次梯度常数)g的物像等大法,所得结果表明该方法有实用价值,同时可简化测量设备。
In this paper, the method of measuring the optical parameters of the self-focusing lens is proposed. The proposed method can measure the axial refractive index n_0 and the focusing constant (quadratic gradient) g of the self-focusing lens simultaneously. The results show that this method is practical Value, while simplifying the measurement equipment.
