A sensing arrangement ( 11 ) for sensing objects at a plurality of sensing sites ( 64 ) is described herein. In one embodiment the arrangement comprises: an imaging device ( 60 ) having an array of light-detecting elements; a light guide arrangement ( 62 ) extending from the sensing sites ( 64 ) to the imaging device ( 60 ); a mount ( 79 ) for maintaining the light guide arrangement ( 62 ) and the imaging device ( 60 ) in a fixed spatial relation so that each sensing site ( 64 ) illuminates a zone ( 60 a,b) of different elements on the array; and a processor ( 72 ), in communication with the imaging device ( 60 ), for analyzing image data captured by each zone. A method of sensing an object is also described herein.
