Abstract

Measurements of the output signal-to-noise ratio for several screen-film systems are made in terms of the noise equivalent number of recorded quanta (NEQ). Described in this way, the signal-to-noise ratio is shown to be a strong function of both exposure and spatial frequency, with significant changes from system to system.
