Abstract
A system of lasers and detectors to detect the presence of objects and determine their speed is disclosed. The system comprises of a pair of lasers and a pair of detectors focused through a single lens or a pair of lenses. An electronic board that accompanies the lasers and detectors is used to provide the logic and decision making mechanism. Data collected and processed by the system yields such information as whether an object is present, whether the object is stationary or is moving, and subsequent speed information. The described system is also capable of providing additional information concerning the characteristics of the moving object such as its profile and length, and indication of a traffic violation.
