Koherenssiaika
Koherenssiaika is a Finnish term that translates to "coherence time" in English. It refers to the duration over which a wave or signal maintains a predictable and stable phase relationship, which is essential in various fields such as physics, optics, and telecommunications. Coherence time is a crucial concept for understanding the quality and stability of light sources, especially in laser technology, where a longer coherence time indicates a narrower spectral bandwidth and improved beam quality.
In physics, coherence time is inversely proportional to the spectral width of a source. For example, a
In telecommunications, coherence time influences the performance of fiber-optic communication systems. Longer coherence times enable better
Overall, coherence time is a fundamental parameter in analyzing the behavior of waves and signals. Its measurement
