Summary

The ability to efficiently detect single photons is critical in a range of applications, from quantum information science and optical communications to medical imaging and LiDAR. To preserve vital data during research, every photon event must be accurately counted and timestamped. This requirement places stringent demands on the detection hardware, including picosecond-scale time resolution and zero dead time between events.

In this webinar, Liquid Instruments will share how reconfigurable, FPGA-based instrumentation can fulfill both criteria with flexibility and speed. Learn how a digital time and frequency analyzer can track up to four events simultaneously, while achieving a time resolution on the order of 10 ps with zero dead time. Join us to see how flexible instrument capabilities including adjustable event thresholds, timestamping, and optional analog outputs enable a wide variety of single-photon detection applications.

You’ll also see several live demonstrations, ranging from a Hanbury-Brown-Twiss (HBT)-like correlation measurement to decoding pulse-position modulated (PPM) data. A Q&A session will follow the demonstration.
