What is it about?
The problem of spatial coherence applied to confocal optical systems is investigated. The coherence factor or the mutual coherence intensity, assuming perfectly coherent illumination and partially coherent detection, is calculated. This detection step is dependent upon the pinhole diameter of the receptor. The optimal diameter of the pinhole receptor is discussed.
