The present invention provides various apparatus and methods for detecting laser beams, locating their origin, recording these events, and alerting law enforcement agencies as the event unfolds. The apparatus includes at least two communicably coupled camera systems coupled to one or more image processors. A method for detecting the laser beam includes the use of optical, temporal and two-dimensional spatial image filtering. A method for computing the location of the laser beam consists of performing geometric computations using triangulation techniques and physical surveying of the cameras. A method for communicating the location of the laser beam in real-time includes the use of wired or wireless communications means, including the coordination with local air traffic control information.

1. An electro-optical method for detecting the presence of one or more laser beams pointed skyward comprising the steps of: providing a first apparatus for acquiring a first electronic image of a first scene or first region, the first apparatus comprising a first image detector camera configured to acquire an image of the first scene facing the first camera, and at least one communicably coupled digital image computing processors;acquiring the first electronic image of the first scene using the first image detector camera;modifying the first electronic image based on one or more image improvement parameters using the one or more communicably coupled digital image processors to generate a modified first image; anddetermining the existence or non-existence of a thin straight line within the modified first image to determine the presence of the one or more laser beams. 2. The electro-optical method as recited in claim 1, further comprising a second apparatus similar in function to the first apparatus, acquiring a second scene image facing a second image detector camera of the second apparatus, whereby the second scene image is physically different from the first scene. 3. The electro-optical method as recited in claim 2, further comprising a first communications coupling between the first and the second apparatus. 4. The electro-optical method as recited in claim 3, further comprising a second communications coupling between the first and/or second apparatus and an external communications channel, communicating: a presence of said one or more laser beams;a location of the source of said one or more laser beams; ora location of air traffic in the vicinity of the first and/or second apparatus. 5. The electro-optical method as recited in claim 2, where at least one of the first and second apparatus is mechanically fixed to a single location. 6. The electro-optical method as recited in claim 2, where at least one of the first and second apparatus is not mechanically fixed to a single location. 7.
