  • The meaning of coherence in coherent optical modules

    The meaning of coherence in coherent optical modules

    In optics, coherence means a light wave keeps a steady phase relationship at different spots or times. If a source is only partly coherent, you'll see reduced or fluctuating visibility in the patterns. Partially coherent sources are sources where the coherence time or coherence length are limited by bandwidth, by thermal noise, or by other effect. Know the definition of fringe contrast.
