WebWe describe the fabrication and evaluation of a fiber-coupled, photon-number-resolving TES detector optimized for absorption at 1550 and 1310 nm wavelengths. The measured system detection efficiency at 1556 nm is 95 % ± 2 %, which to our knowledge is the highest system detection efficiency reported for a near-infrared single- photon detector. WebWe demonstrate the absolute depth map recovery at ranges between 2.2 km and 13.8 km using ∼1.41 signal photons per pixel. We also show the capability to image the absolute distances of moving targets in real time. © 2024 Optica Publishing Group Full Article PDF Article More Like This
