Towards commercialization of compressed optical-streaking ultrahigh-speed photography (COSUP) (Phase 1)

单次超高速成像对于实时捕捉物理、生物、化学等领域的瞬变现象具有重要意义。然而，现有技术的应用范围有限、序列深度低或像素计数有限。为了克服这些限制，我们最近发明了一种新的摄影技术-压缩光学条纹超高速摄影(COSUP)，它将被称为压缩传感的计算成像方法集成到标准CMOS相机的图像采集过程中。在这方面，在不修改传感器结构的情况下，通过使用所有现成的组件，COSUP显示出将CMOS相机的成像速度提高了四个数量级以上。作为一种通用的成像平台，COSUP适用于大多数现有的CCD和CMOS相机，并且可以用于宽波长范围和获取各种光学特性，如偏振。除了科学实验，COSUP还准备帮助其他社区，包括电影业和体育摄影。最后，与现有的超高速相机相比，COSUP是一种非常经济的选择。由NSERC和INRS资助的一项市场研究表明，COSUP具有巨大的商业利益。 NSERC I2I第一阶段项目旨在将COSUP技术进一步开发为商业产品。总而言之，提出了三个目标：将概念验证COSUP系统集成到紧凑的原型中，提高COSUP的图像重建速度，以及使用COSUP原型演示超高速成像。雄厚的技术基础和经验丰富的团队将确保该项目的按时实施和快速进展。在整个项目中，我们将与我们的行业合作伙伴密切合作，以实现未来的技术转让和设备商业化。

Single-shot ultra-high-speed imaging is of great significance to capture transient phenomena in physics, biology, and chemistry in real time. Existing techniques, however, have a restricted application scope, a low sequence depth, or a limited pixel count. To overcome these limitations, we recently invented a new photography technology-termed compressed optical-streaking ultra-high-speed photography (COSUP), which integrates the computational imaging method termed compressed sensing into the image acquisition process of a standard CMOS camera. In this regard, without modifying the structure of the sensor and by using all off-the-shelf components, COSUP exhibits the enhancement of the imaging speed of a CMOS camera by over four orders of magnitude. As a universal imaging platform, COSUP is suitable to most existing CCD and CMOS cameras, and can be used for a wide range of wavelengths and for acquiring various optical characteristics such as polarization. Besides scientific experiments, COSUP is poised to aid other communities, including the movie industry and sports photography. Finally, COSUP is a significantly economical alternative to existing ultra-high-speed cameras. A market study funded by NSERC and INRS has demonstrated a huge commercial interest in COSUP. This NSERC I2I Phase I project aims to further developing the COSUP technique toward a commercial product. In total, three Aims are proposed to integrate the proof-of-concept COSUP system into a compact prototype, to improve image reconstruction speed in COSUP, and to demonstrate ultrahigh-speed imaging using the COSUP prototype. The solid technical foundation and highly experienced team will ensure the on-time execution and fast progress of this project. Throughout this project, we will closely work with our industrial partners for future technology transfer and device commercialization.
