ABSTRACT:
A sensor and detection system is included. The sensor includes at least one transmitter which has associated optical elements for emitting at least one light beam toward the object to be detected. At least one receiver is positioned adjacent the transmitter for receiving light reflected from an edge of the object. The receiver generates a signal responsive to the reflected light. The associated optical elements of the transmitter include a converging lens for emitting a focused light beam in one plane, and a cylindrical lens for emitting a diverging light beam in another plane, such that a portion of the reflected light is diverging and is received by the receiver over a wide angle of coverage.
