The Role Of Screen And Film In Determining The Noise-Equivalent Number Of Quanta Recorded By A Screen-Film System

We apply an existing model for the relationship governing the DQE characteristics of a screen-film system to the calculation of absolute values of the noise-equivalent number of quanta (NEQ). The roles of the screen and film are investigated separately, and the influence of interactive properties such as screen amplification and grain size is explored. Hence factors limiting the NEQ of existing screen-film systems are identified.
