WebApr 10, 2024 · Future research on charge-coupled devices, which scientists use to detect photons, will take place in the CCD lab on the ground floor of IERC. This lab is an example of the typical high-bay space that the building provides. The infrastructure in these spaces provides clean power, grounding bars, compressed air, nitrogen and vacuum hook-ups. WebSingle-photon light detection and ranging (LiDAR) has broad applications ranging from remote sensing to target recognition. In most cases, however, the repetition period of the pulsed laser limits the maximum distance that can be unambiguously determined. The relative distances are normally obtained using a depth map. Here, we propose and …
