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.
