70 . The method of claim 63 , further comprising determining, by the processor and based on (i) the information obtained from the interruption of a portion of the first array of light beams, (ii) the interruption of a portion of the second array of light beams, and (iii) the distance between the plane of the first array of light beams and the plane of the second array of light beams, a speed of an object causing the interruption.

71 . The method of claim 60 , further comprising determining, by the processor, the interruption of a portion of the first array of light beams and the interruption of a portion of the second array of light beams are caused by different persons.

72 . The method of claim 60 , further comprising guiding a person to pass through the first array of light beams and the second array of light beams via use of a guiding structure.

73 . The method of claim 60 , wherein each photoelectric unit in the first planar array is configured to receive a reflected copy of the light beam generated by such photoelectric unit.

74 . The method of claim 60 , further comprising determining, by the processor and based on the interruption of a portion of the first array of light beams and the interruption of a portion of the second array of light beams, whether a person is entering the specified area or exiting the specified area.

75 . A system for quantifying flow of persons through an entrance point of a specified area, the system comprising:

a first planar array of photoelectric units disposed on a first side of the entrance point;

a second planar array of photoelectric units disposed on the first side of the entrance point;
