Spectral-Depth Imaging (SDI), within the fast-paced domain of computational imaging, stands at the crossroads of exciting potential and significant challenges. This unique technology, known for its ability to concurrently gather spatial, spectral, and depth particulars, has far-reaching implications across varied sectors from astrophysics and biochemistry to security and remote sensing. Its significant impact within computer vision, notably in target classification and recognition via depth and spectral data, is irrefutable. Traditional SDI systems have primarily leveraged multiple sensors or scanning processes to amass comprehensive optical information, posing certain challenges for dynamic detection. Snapshot SDI, characterized by modulation of optical data in single-sensor measurements, has emerged as a potentially transformative solution, with promising advancements in the reconstruction of data through computational algorithms.

The overarching goal of this research topic is to delve further into the potential of spectral-depth imaging, specifically focusing on snapshot SDI. The primary aim is to address challenges related to the degradation of image quality, the precision around spectral data, and the spatial-spectral resolution of reconstructed data. Key objectives include the conceptualization and implementation of new snapshot SDI principles and recovery algorithms for enhanced 4D data quality. Additionally, the development of innovative algorithms and computational techniques to further single-sensor measurement data modulation, alongside advancements in the multi-sensor data reconstruction methods, forms an integral part of this research. Lastly, it embarks to create and examine new deep learning applications to tackle inverse issues in snapshot SDI, while also exploring ways to enhance the optical structure of snapshot SDI and the spatial-spectral resolution of reconstructed data. This project aims to revolutionize computational imaging and data recovery mechanisms, thereby shaping new paradigm shifts in the realm of SDI.
