    摘要： A system (4) for use in an automobile (2) for the detection of objects comprising: a light source (6); a plurality of spaced transmitter ports (10, 12) for respectively transmitting light to a plurality of fields of illumination (18, 20); an optical fiber coupling the light source to the transmitter ports; a plurality of receiver ports (10, 12) embracing respectively a plurality of fields of reception (34, 36) each having an area of overlap (38, 40, 42, 44) with each of the plurality of fields of illumination so as to receive light transmitted from one of the transmitter ports and reflected by an object present in an area of overlap; a receiver (22) for receiving light and for producing a signal representative thereof; an optical fiber (24) coupling the receiver ports to the receiver; and processing means (52) for sequentially activating each of the transmitter ports with each of the receiver ports, and for processing the signal produced by the receiver in response to each activation to detect the presence of an object in each of the areas of overlap.
