Market Study of Dispersion-Eliminated Coded Aperture Light-Field (DECALF) Imaging

光场成像可以记录入射光线的二维(2D)空间(x，y)和2D角度(？，f)信息。到目前为止，光场成像已经广泛应用于显微镜、摄影和内窥镜检查。根据MarketandMarkets的数据，到2026年，轻油田市场规模预计将达到1.54亿美元，而2021年的估计规模为7600万美元。推动光场市场增长的因素来自电影和游戏中不断改进的视觉技术、定制营销、对原型的需求不断上升以及医学成像。针对现有方法难以同时获得高空间分辨率和高角分辨率的问题，提出了一种利用宽带可见光在视频率下实现高分辨率彩色光场采集的色散消除编码孔径光场成像系统。DECALF成像系统使用双数字微镜器件(DMD)设计来补偿整个可见光光谱中的色散，以20赫兹的频率捕获1280×1024×5×5(x，y，？，f)彩色光场图像。使用静态和动态三维(3D)彩色场景，我们实验演示了DECALF成像系统的多视角查看、数字重新聚焦和3D跟踪。我们还将其应用于自由活动的正常斑马鱼和疾病模型斑马鱼的逃逸行为的成像和分析。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，并有望在许多工业和科学领域得到应用。在这方面，NSERC I2I市场研究将有助于确定最有前景的应用，分析潜在市场的前景，并促进技术从实验室转移到商业产品。

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.
