Quantum-limited detection of arrival time and carrier frequency of time-dependent signals
Patrick Folge, Laura Serino, Ladislav Mišta +4
Precise measurements of both the arrival time and carrier frequency of light pulses are essential for time-frequency-encoded quantum technologies. Quantum mechanics, however, impos…

Sampling the spatial coherence of light
M. Vitek, M. Peterek, D. Koutny +6
We introduce a novel application of the Hartmann sensor, traditionally designed for wavefront sensing, to measure the coherence properties of optical signals. By drawing an analogy…
