Conventionally, the acquisition of the 5D (x, y, u, v,λ) spectral light field (5D-SLF) data cube relies on bulky and expensive camera arrays, which are impractical for widespread application. Existing single-detector systems are fundamentally limited by a trade-off between the resolutions of different dimensions owing to insufficient coding capabilities. Here we introduce an Aperture-aware Dispersion Light-field Imaging Spectrometer (ADLIS), that targets a synergy between compactness and resolution through aperture-multiplexed modulation, leveraging the inherent spectral-filtering properties ofbirefringent material. Using only a manufacturing-friendly and cost-effective phase plate made of birefringent quartz crystal, the aperture of the proposed ADLIS enables compact angularspectral encoding that is highly sensitive to both the incident angle and spectrum of incoming light. In contrast to the viewpointseparation approach of microlens arrays, ADLIS employs aperture encoding to superimpose all viewpoints onto each sensor pixel. This shifts the design paradigm from spatial division to encoding integration, aiming to achieve full-resolution light field recovery. Thus, we develop the Aperture-aware Dispersion Lightfield Imaging (ADLI) framework, which optimizes the aperture design and 5D-SLF reconstruction in an end-to-end (E2E) manner. Trained by simulation data and validated through real-world experiments, our system achieves robust high-performance 5DSLF imaging while maintaining full spatial resolution.  \nIndex Terms—Computational Imaging, Deep Optics, Spectral Light-field.  \nI. INTRODUCTION  \nHIGH-DIMENSIONAL light-field imaging is a pivotal  \nfrontier for advanced visual perception. Light-field imaging [1], [2], [3], [4] overcomes the limited angular resolution of conventional planar imaging by capturing light rays from multiple viewpoints. Analogously, spectral imaging [5], [6], [7], [8], [9], [10], [11], [12] introduces perceptual capabilities across the spectral domain, empowering visual sensing technologies to probe intrinsic material properties of objects and thereby offering solutions for industrial inspection, material identification, and metamerism recognition. Furthermore, 5D-SLF imaging, which integrates mult-dimensional information to enable the acquisition of high-dimensional data,  \nChenglong Huang, Tao Lv, Jianing Yang, Chongde Zi, Linsen Chen and Xun Cao are with Nanjing University, Nanjing, 210023, China.
