Market Study of Compressed Optical-Streaking Ultra-high-speed Photography (COSUP)

现有的相机建立在电荷耦合器件(CCD)和互补的金属氧化物半导体(CMOS)传感器的基础上，在各种应用中都是不可或缺的，从使用智能手机进行日常拍照到高灵敏度测量科学级相机。正如MarketSandMarkets在2018年1月报告的那样，2016年其全球市场规模为127.8亿美元。预计2023年将以9.75%的复合年增长率扩大到248亿美元。然而，大多数现有的硅胶相机的成像速度中等，最高可达每秒200帧。为了克服这一限制，人们发明了许多高速摄像机，但它们都有各种缺点，包括视场缩小、灵敏度损失、结构庞大复杂、每次采集的帧数量有限。更重要的是，它们的价格很容易超过10万美元。最近，我们发明了一种新的摄影技术-压缩光学条纹超高速摄影(COSUP)-可以克服这些限制。该方法将一种称为压缩感知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，可以用于宽波长范围的成像，并可用于获取各种光学特性，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。

Existing cameras, building upon the charge-coupled devices (CCDs) and the complementary metal-oxide-semiconductor (CMOS) sensors, are indispensable in diverse applications, ranging from daily photo-shooting using a smartphone to high-sensitivity measurements scientific-grade cameras. As MarketsandMarkets reported in January 2018, its global market size was valued at USD 12.78 billion in 2016. It is anticipated to expand at a compound annual growth rate of 9.75% to reach a value of 24.80 billion USD in 2023. However, most existing silicon cameras have moderate imaging speeds up to 200 frames per second. To overcome this limitation, many high-speed cameras have been invented, but they all have various drawbacks, including a reduced field of view, loss of sensitivity, bulky and complicated structures, a limited number of frames in each acquisition. More importantly, their price is easily over USD 100 thousand.Recently, we invented a new photography technology-termed compressed optical-streaking ultra-high-speed photography (COSUP)-that can overcome these limitations. The new method 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, COSUP 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 movie industry and sports photography. Finally, COSUP is a significantly economical alternative to existing ultra-high-speed cameras.
