Many important physical mechanisms are manifested in ultrafast optical phenomena that are often either non-repeatable or difficult-to-reproduce. Single-shot ultrafast optical imaging is the only viable solution to record the entire process of these events within the duration of its occurrence. Among existing approaches, compressed ultrafast photography (CUP) has emerged to be a promising technique. Exhibiting the world's fastest camera, CUP has an imaging speed of 10 trillion frames per second and can capture both spatial and temporal information in a single camera exposure. However, restricted by operational spectrum and image speeds, existing CUP systems have a limited application scope in imaging nonlinear light-matter interactions. In response to these limitations, in this CRD grant application, we propose to develop the next-generation of CUP systems for single-shot multi-parameter ultrafast optical imaging of nonlinear light-matter interactions at unprecedented imaging speeds. In collaboration with two Canadian industrial partners, we plan to develop three new CUP prototypes upon their existing commercial products and core expertise, which will enable, for the first time, sensing the refractive index perturbation, imaging multiple wavelengths simultaneously from the visible-to-near-infrared spectrum, and reaching 100 trillion frames per second imaging speed. Targeting a billion-dollar potential market in multiple fields of optics, the proposed systems hold great commercial potential. Capitalizing on the core expertise of both companies, these new systems are highly complementary to their existing products. Scientifically, these systems will greatly enhance the CUP camera's specifications in contrasts, operational spectrum, and imaging speeds, which in turn, will allow unprecedented observation of ultrafast light-matter interactions with applications in optical physics, materials characterization, and data storage. Exerting great social-economic significance to Canada, this CRD application will also create excellent opportunities to train and retain HQP, promote knowledge-based economy, and solidify Canada's position as a world leader in photonics and optics.

超快光学现象表现出许多重要的物理机制，这些现象通常是不可重复或难以生产的。单光超快光学成像是唯一在发生在其发生持续时间内记录这些事件的整个过程的唯一可行解决方案。在现有方法中，压缩的超快摄影（CUP）已成为一种有前途的技术。杯子展示了世界上最快的相机，其成像速度为每秒10万亿帧，并且可以在单个相机曝光中捕获空间和时间信息。但是，受操作频谱和图像速度的限制，现有的杯系统在成像非线性光 - 摩擦相互作用方面的应用范围有限。 为了应对这些局限性，在此CRD赠款应用中，我们建议开发杯子系统的下一代，用于以前所未有的成像速度以非线性光剂相互作用的单参数超快光学成像。我们计划与两个加拿大工业合作伙伴合作，以其现有的商业产品和核心专业知识开发三个新的杯子原型，这将首次使屈光索引扰动感知屈光索引扰动，从而从可见的网络范围同时成像多个波长，并从可见的网络范围内进行100亿美元的每次数字小型FrameS Speedss Speedss Speeds Speed。 拟议的系统针对多个光学领域的数十亿美元潜在市场具有巨大的商业潜力。利用两家公司的核心专业知识，这些新系统与其现有产品高度互补。从科学上讲，这些系统将在对比度，操作范围和成像速度中极大地增强杯子摄像头的规格，从而使超快光结物与光学物理，材料表征和数据存储中的应用相互作用的前所未有地观察到。这项CRD应用程序对加拿大发挥了极大的社会经济意义，还将为培训和保留HQP，促进基于知识的经济，并巩固加拿大在光子学和光学领域的世界领导者的地位。
