Evaluation of a device for indirect assessment of automatic exposure control systems.
A test device which can indirectly measure the performance of an automatic exposure control system and which offers the potential to reduce the time and film requirements for such tests has been evaluated. Evaluation results demonstrate that the device can successfully predict image optical density to within +/- 0.10 optical density units over a wide range of imaging technical factors and image optical densities.
