Optimization for optical characteristics of WFC mask of mobile phone imaging system

  • 摘要: 设计了基于波前相位编码板的轻薄手机镜头,原始成像系统的焦深大小是0.017 mm,使用立方相位编码板,采用基于斯特列尔比的相位板优化方法,保持了在不同离焦位置成像系统MTF的稳定性,最终成像系统设计焦深达到0.136 mm,焦深扩展了8倍,经过Zemax软件仿真,验证了景深延拓的效果。设计结果表明,使用相位编码板即可增大定焦距手机系统的景深,使得系统结构紧凑,又克服了视场效应。
    Abstract: A compact mobile phone lens based on the wavefront coding(WFC) was designed, the depth of field (DOF) of the original system was 0.017 mm. The cubic phase mask (CPM) was utilized and the parameters of phase mask could be optimized base on Strehl ratio (SR) to keep the stability of the modulation transfer function (MTF) at different positions. Finally the designed DOF reached 0.136 mm,which extended 8 times. The effect of DOF extension was verified by simulation through Zemax software. Results indicate that it can increase the DOF of fixed mobile phone system,make the structure compact as well as overcome the field effect through using WFC.
