1. A sensor device for determining a position of a light source, the sensor device comprising:
a plurality of sensor units, each sensor unit of the plurality of sensor units having a respective sensor area; and
a mask disposed above the plurality of sensor units and arranged such that incident light from the light source will illuminate different regions of the sensor area of each sensor unit of the plurality of sensor units depending on a position of the light source relative to the sensor device, so that the position of the light source may be determined based on which regions of the sensor areas of the plurality of sensor units are illuminated;
wherein each sensor unit of the plurality of sensor units is arranged to be controlled by a respective unit controller of a plurality of unit controllers to determine the position of the light source;
wherein each sensor unit of the plurality of sensor units comprises a first strip and a second strip arranged substantially orthogonal to the first strip, and wherein the mask is arranged such that the light source will illuminate regions of the first strip and the second strip of each sensor unit simultaneously.
