Light field imaging can record two-dimensional (2D) spatial (x,y)and 2D angular (?,f) information of incident rays. To date, light field imaging has been widely implemented in microscopy, photography, and endoscopy. According to MarketsandMarkets, the light field market size is projected to reach US$ 154M by 2026 from an estimated US$ 76M in 2021. The factors driving the growth of the light field market come from the improving visual technology in movies and games, customized marketing, escalated need for prototyping, and medical imaging. However, existing approaches are strained by attaining high spatial resolution and high angular resolution simultaneously.Here, we develop a dispersion-eliminated coded-aperture light field (DECALF) imaging system for high-resolution, color light field acquisition using broadband visible light at video rate. Using a dual digital micromirror device (DMD) design to compensate for dispersion in the entire visible spectrum, the DECALF imaging system captures 1280×1024×5×5 (x,y,?,f) color light field images at 20 Hz. Using static and dynamic three-dimensional (3D) color scenes, we experimentally demonstrate multi-perspective viewing, digital refocusing, and 3D tracking of the DECALF imaging system. We also apply it to the imaging and analyses of escape behaviors of freely moving normal and disease-model zebrafish. As a universal imaging scheme, the DECALF system is expected to be integrated into a variety of modalities for both macroscopic and microscopic light field imaging and is envisioned to find many industrial and scientific applications. In this regard, this NSERC I2I Market Study will assist in identifying the most promising applications, analyzing the prospect of the potential market, and facilitating technology transfer from the laboratory to a commercial product.

光场成像可以记录二维（2D）空间（x,y）和二维角度(？，f)入射光线信息。迄今为止，光场成像已广泛应用于显微镜、摄影和内窥镜检查。根据MarketsandMarkets的数据，到2026年，光场市场规模预计将从2021年的7600万美元达到1.54亿美元。推动光场市场增长的因素来自于电影和游戏中不断改进的视觉技术、定制营销、原型设计需求的升级以及医疗成像。然而，现有的方法在同时获得高空间分辨率和高角度分辨率方面存在一定的局限性。在这里，我们开发了一个色散消除编码孔径光场（DECALF）成像系统，用于高分辨率，彩色光场采集，利用宽带可见光在视频速率。使用双数字微镜装置（DMD）设计来补偿整个可见光谱中的色散，DECALF成像系统捕获1280×1024×5×5 (x,y,？，f) 20 Hz的彩色光场图像。利用静态和动态三维（3D）彩色场景，我们实验演示了DECALF成像系统的多视角观看、数字重聚焦和3D跟踪。我们还将其应用于正常斑马鱼和疾病模型斑马鱼自由运动的逃脱行为的成像和分析。作为一种通用成像方案，DECALF系统有望集成到宏观和微观光场成像的各种模式中，并有望找到许多工业和科学应用。在这方面，这项NSERC I2I市场研究将有助于确定最有前途的应用，分析潜在市场的前景，并促进技术从实验室转化为商业产品。
