摘　　要：采用离子交换工艺和精密加工技术制作了方形自聚焦透镜5×5阵列,并对其成像特性进行研究。结果表明:方形自聚焦透镜阵列相对于圆形孔径阵列而言,能有效增大填充系数,提高受光面积,其多重像和综合像的像质均匀,成像质量好。分析了导致多重像偏离和综合像变形的原因,并给出解决这一问题的关键技术。The 5× 5 square GRIN lens array was manufactured with the ion-exchanging technique and precision processing technology. The imaging properties of the array were studied. The results show that, compared with circular aperture GRIN lens array, the square aperture GRIN lens array can effectively increase the filling coefficient and active optical area, and its multiple image and synthetic image have better imaging quality. The reasons of the multiple image＇s deflection and synthetic image＇s deformation are analyzed. The solution for the problem is presented.
