Abstract

A photodetector, coupled to a computer via an AC-DC converter (capacity 8 or 12 bit) is used to monitor the time changes in daylight illumination. In particular, a picture of the successive (percent) changes in lighting is given by averaging input data across pre-established time blocks, to refer to "frequencies" of importance from the biological stand point. This assessment of the instability of lighting, on a fine time scale, might be of importance for those systems, like human vision (and, why not, robotic vision), working on a differential sensitivity basis, and where the input is controlled by servomechanisms.
