摘要
This study introduces the concept of a liquid-filled lens module; the module is composed of a flexible lens membrane, a flexible sensor membrane that is constructed by attaching sensor chips onto a flexible substrate and transparent liquid that fills the space between the flexible lens membrane and the sensor membrane. The image quality of the liquid-filled lens module is comparable to that of a solid lens module with a flat-type image sensor. However, the liquid-filled lens module has the advantages of requiring fewer parts, having better optical aberration compensation, a wider image range. This study identifies the optimized conditions for the sensor membrane to fulfill the Petzval surface of the optical module and the compensation mechanism of the flexible lens and the sensor membranes. The simulation results show that the distortion aberration, the field of curvature and the Modulation Transfer Function are good.
