Coherence measurement
WebApr 21, 2024 · A scanning tunneling microscope (STM) combined with a pump-probe femtosecond terahertz (THz) laser can enable coherence measurements of single molecules. We report THz pump-probe measurements that demonstrate quantum sensing based on a hydrogen (H 2) molecule in the cavity created with an STM tip near a surface.

The aim of the study was to determine if the presence of intraretinal cysts is positively correlated with diagnosis of … WebWe measure the complex-valued spatial coherence function of a multimode broad-area laser diode using Young’s classical double slit experiment realized with a digital micromirror device. We use this data to construct the coherent modes of the beam and to simulate its propagation before and after the measurement plane.

In signal processing, the coherence is a statistic that can be used to examine the relation between two signals or data sets. It is commonly used to estimate the power transfer between input and output of a linear system. If the signals are ergodic, and the system function is linear, it can be used to estimate the … See more The coherence (sometimes called magnitude-squared coherence) between two signals x(t) and y(t) is a real-valued function that is defined as: $${\displaystyle C_{xy}(f)={\frac { G_{xy}(f) ^{2}}{G_{xx}(f)G_{yy}(f)}}}$$ where Gxy(f) is the See more Here we illustrate the computation of coherence (denoted as $${\displaystyle \gamma ^{2}}$$) as shown in figure 1.
