- 요약Modern imaging systems increasingly rely on computational methods to extract high-dimensional information from 2D optical measurements. Examples include snapshot 3D microscopy systems that capture volumetric data in a single exposure and hyperspectral imagers that simultaneously measure spatial and spectral information across dozens of wavelength channels. Designing such systems is challenging because it requires jointly optimizing both the optical hardware that encodes the scene and the computational algorithms that decode the measurements, a process complicated by the non-convex, high-dimensional parameter spaces and computationally expensive end-to-end training requirements. In this dissertation, we present data-driven approaches that address these challenges through physics-based simulation and information-theoretic design principles. We first develop a memory-efficient, end-to-end pipeline that jointly optimizes optical elements and neural reconstruction algorithms using differentiable simulation, demonstrating this method on a snapshot 3D fluorescence microscope that achieves improved resolution over heuristic designs. We then present a compact snapshot hyperspectral fluorescence microscope with a custom iterative reconstruction algorithm tailored to its physical model.To overcome the computational limitations of end-to-end optimization and accommodate non-differentiable reconstruction algorithms, we develop an information-theoretic optimization framework that treats optical design as a mutual information maximization problem. This approach, implemented through the IDEAL and IDEAL-IO methods, decouples encoder design from specific reconstruction implementations. By directly maximizing the information content of measurements rather than optimizing reconstruction fidelity, this framework provides a generalizable design principle that transcends particular decoder architectures while reducing the computational requirements in comparison to end-to-end design.The methods developed in this dissertation demonstrate that principled, simulation-driven design can achieve improved performance across diverse high-dimensional imaging modalities while maintaining computational tractability.
