Abstract
Apparatus comprising: a sensor configured to generate sensor output dependent on an intensity of light incident on the sensor and having a field of view directed at an external surface in use; an illumination source configured to emit light onto the external surface in use; a window located such as to allow light to pass from the illumination source to the external surface and to allow light to pass to the sensor from the external surface in use; a shield coupled to or integral with the window, the shield being substantially opaque to substantially all wavelengths of light detectable by the sensor and defining an aperture which limits the field of view of the sensor; and a processor configured to use the sensor output to determine information associated with reflection characteristics of the external surface.
