- Abstract:
- This article reports the results of a multinational research project investigating visual performance in halflight (mesopic) conditions. From the experimental investigations using reaction time, detection threshold and recognition contrast threshold techniques, the results were used to develop a system for practical mesopic photometry, which provides an acceptably good fit to the experimental data and is also suitable for practical implementation by the lighting industry. A major feature of the model is that it can be implemented in terms of photopic and scotopic luminance measurements, measurements that can easily be made in practice.
