An optical interferometric LiDAR system to control the main measurement range using active selection of a reference optical path length according to an absolute position of an x-x-x-object to be measured, including: a laser source unit configured to emit light having a variable wavelength; a light dividing unit configured to divide the light into a variable reference arm and a measurement arm; a variable reference arm having a structure for selecting an optical path length of a reference arm; a measurement arm configured to propagate light and receive light reflected from a target x-x-x-object; and a light detecting unit configured to detect an optical signal generated as light passing through the variable reference arm and light passing through the measurement arm cause optical interference.
