ISO 9334:2012对与光学传递函数有关的术语进行了细化，并在相关情况下指出了这些术语之间的数学关系。它还定义了与光学传递函数测试相关的重要参数。 ISO 9334:2012中定义的术语和参数适用于光学、电光和其他成像系统的光学传递函数的所有测量。

ISO 9334:2012 de-fines terms relating to the optical transfer function and indicates, where pertinent, the mathematical relationships between those terms. It also defines important parameters that should be speci-fied in connection with optical transfer function testing. The terms and parameters de-fined in ISO 9334:2012 apply to all measurements of the optical transfer function for optical, electro？optical and other imaging systems.
