The Design and Optimization of a Distributed Multi-Aperture Light Field Imaging System

We propose a distributed multi-aperture light field imaging system as a solution for the low resolution, small depth of field, and poor imaging quality of traditional optical field imaging systems. A 4 -focal length microlens array is proposed to optimize the imaging system, which can increase the depth of field of the system 6.57 times and have a higher pixel utilization rate. Through ZEMAX, optimize the single microlens by using a double-sided non-spherical surface type. According to simulation results, the system is capable of focusing on different goals at different locations and can produce high-quality images.
