Latest Patents

W Randall Babbitt holds a patent for a "Method and apparatus for measuring distance to a target." This invention employs multiple-frequency intensity-modulated laser radar to perform coordinate measurements. The technology involves a laser diode source that is intensity modulated by varying its excitation current. The output beam is directed to a target using scanning mirrors or other opto-mechanical means, and the light returned from the target is detected. The modulation frequency is alternated between two or more values, creating a dataset of several relative phase measurements that uniquely determine the distance to the target without ambiguity. The device includes a laser modulated by a high-frequency signal generator, optics for directing the output signal, and a computer that calculates phase differences to determine the distance to the target.
