Abstract: The present invention provides a phase calibration method, device, and equipment. The method comprises the steps of: a first light beam emitter generating a first light-wave into a target object, the first light-wave being reflected at the target object and flying back onto a receiver, wherein the first light-wave, as an external beam path signal, is modulated by a first high-frequency oscillation signal; a second light beam emitter emitting a second light-wave into the receiver, wherein the second light-wave, as an internal beam path signal for fundamental phase reference, is modulated by a second high-frequency oscillation signal; and the receiver performing a phase comparison between received first light-wave and sequentially received second light-wave therein and exporting a measurement signal with fundamental reference eliminated. The present method achieves phase compensation and calibration, thereby reducing the influence of environmental elements, increasing measuring precision, and thus reducing system cost.
