Latest Patents
Dan Duan holds a patent for an "Apparatus for precise distance measurement." This apparatus includes a multiple frequency generator, a laser transmitter, an optical receiver, a first measuring unit, a second measuring unit, and a central processing unit. The laser transmitter outputs a light signal to a target, while the optical receiver captures the reflected light signal. It mixes the base frequency signal from the multiple frequency generator with the reflected light signal, subsequently outputting a measurement signal to the first and second measuring units. These units calculate the time difference and phase difference between the light signal and the reflected light signal. The central processing unit then computes the precise distance based on these differences.
