Ul wavefront's
WebA wave front is defined as a surface of constant phase. Thus, the notion of a wave front implies one type of coherence—a lateral phase coherence across the wave front. A beam of light also displays longitudinal coherence—a phase … WebA wavefront is an essential parameter in the propagation of light and can be used to characterize optical surfaces, align optical assemblies or help to improve the performance of optical systems. In this application note, we will cover the most common applications of wavefront sensors and illustrate them with a few examples.
