在量子力学里，相互作用绘景（interaction picture），是在薛丁格绘景与海森堡绘景之间的一种表述，为纪念物理学者保罗·狄拉克而又命名为狄拉克绘景。在这绘景里，描述量子系统的态矢量与表达可观察量的算符都会随着时间流易而演化。有些实际案例会涉及到因相互作用而使得量子态与可观察量发生改变，这类案例通常会使用狄拉克绘景。

狄拉克绘景与薛丁格绘景、海森堡绘景不同。在薛丁格绘景里，描述量子系统的态矢量随着时间流易而演化。在海森堡绘景里，表达可观察量的算符会随着时间流易而演化。

这三种绘景殊途同归，所获得的结果完全一致。这是必然的，因为它们都是在表达同样的物理行为。

In quantum mechanics, the interaction picture (also known as the Dirac picture) is an intermediate representation between the Schrödinger picture and the Heisenberg picture. Whereas in the other two pictures either the state vector or the operators carry time dependence, in the interaction picture both carry part of the time dependence of observables. The interaction picture is useful in dealing with changes to the wave functions and observable due to interactions. Most field theoretical calculations use the interaction representation because they construct the solution to the many body Schrödinger equation as the solution to the free particle problem plus some unknown interaction parts.
