Abstract
A device for detecting an incident light distribution. The device has an array of light sensors, and a shadow casting element spaced above the light sensor array, with the shadow casting element between the incident light to be modeled 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.
