Abstract
This study explored the optimization of multi-layered diffractive optical elements (DOEs) for compressive sensing in imaging systems. We investigated how increasing the number of DOE layers with optimization affected the coherence value of the system's transmission matrix, a key performance indicator for image reconstruction in compressive sensing. Through wave-optics simulations, we demonstrated that coherence decreased monotonically up to 8 layers before increasing, suggesting an optimal layer count exists. Our findings indicated that optimized multi-layer DOEs can significantly enhance the performance of compressive sensing applications, potentially improving accuracy in snapshot super-resolution and multi-dimensional imaging.
