Abstract:
A method for evaluating distance from a first point to a second point. The method includes the steps of generating a periodic binary sequence, generating a harmonic modulation signal, generating a modulated light signal at a range finding device, wherein the modulated light signal is generated based upon the periodic binary sequence and the harmonic modulation signal, transmitting the modulated light signal from the first point toward an object at the second point, receiving a reflected light signal from the object, and determining a distance between the first point and the second point based upon a phase evaluation of periodic binary sequence and harmonic modulation signal of both the transmitted light signal and the received light signal.
