WebCoherence is one of the unique properties of laser light. It arises from the stimulated emission process which provides the amplification. Since a common stimulus triggers the emission events which provide the amplified light, the emitted photons are "in step" and have a definite phase relation to each other. This coherence is described in ... WebSep 7, 2024 · Reflection strength and phase is dependent on the geoacoustic properties of the ocean bottom and may contribute to coherence loss in the recorded sound along with the noted variations in bathymetry. As the receiving array was towed along transect 10, additional reductions in measured coherence arose from the varying bathymetry, ocean …
