Abstract: A device for detecting an incident light distribution comprises an array of light sensors (54), and a shadow casting element (52) spaced above the light sensor array, with the shadow casting element between the incident light to be modelled and the sensor array. A processor interprets a cast shadow detected by the light sensor array thereby to derive information relating to the directional distribution of the incident light.
