【 摘 要 】

In quantum optics (optical coherence) theorem, many sources are employed in the laboratory are secondary planar sources. A source of this kind is usually an aperture in an opaque planar surface screen, illuminated either directly or via an optical system with primary sources. The expression following into the formulation of the radiation in radiant intensity which, analytical solution has not given the time evolution of amplitude. In this research, we consider this problem in quantum field theory (QFT) view point. By using the method of study based on a configuration space for explaining characteristic of the complete process, which begins and ends with the vacuum state so-called vacuum-to-vacuum transition amplitude between emitters and detectors. Propose in this research, we attend and explain the radiation for radiant intensity with time evolution process. To calculation amplitude transition of massive quantum particles propagator stimulated emission by secondary planar surface sources in space-time. Finally, we use the mathematical program for corresponding numerical evaluations between quantum optics and quantum field theory situation.
