Temporally-multiplexed dual-frequency terahertz imaging at kilohertz frame rates
Lucy A. Downes, C. Stuart Adams, Kevin J. Weatherill
We present a temporally-multiplexed dual-colour terahertz (THz) imaging technique using THz-to-optical conversion in atomic vapour. By rapidly alternating the pump laser frequency,…
Virtually structured illumination for terahertz super-resolution imaging
James P. Fleming, Lucy A. Downes, John M. Girkin +1
We demonstrate structured illumination super-resolution imaging in the Terahertz (THz) frequency band using the Virtually Structured Detection (VSD) method. Leveraging our previous…
Determination of Quantum Defects and Core Polarizability of Atomic Cesium via Terahertz and Radio-Frequency Spectroscopy in Thermal Vapor
Gianluca Allinson, Lucy A. Downes, Kevin J. Weatherill +1
We present new measurements of quantum defects and core polarizabilities in cesium (Cs), based on transition frequency measurements between Rydberg states ($14 \leq n \leq…
