 CASPY, Collaborative Photon Processing for Active Single Photon Imaging, is a new technology designed to improve the performance of single-photon cameras by taking advantage of the correlation between photons. This technology can be used across multiple applications such as LiDAR imaging and LIF cell fluorescence imaging. It has been shown to work well in a variety of lighting conditions, including low-photon counts and high-ambient light. The technology is expected to become a standard feature in future single-photon cameras. This article was authored by Jong Ho Lee, Atul Ingle, Jenny V Choco, and others.
