An optical field matching filtering range finding device based on M-sequence phase coding comprises a high-speed phase modulating and transmitting end, and a low-speed receiving end. The optical field matching filtering range finding device has advantages of high-speed modulation, high-speed receiving, random distribution for detecting light and reference light strength, no requirement for electronic signal processing, no range finding result effect by target echo waveform interference from multiple distances. A rectangular prism which is driven by a stepping motor is used for adjusting time delay of local reference light, so that a phase coding signal is focused through matched filtering. A relative distance between target points is measured through light path delay of the stepping motor. The optical field matching filtering range finding device acquires distance information through a high-speed phase coding signal, and can obtain a relatively high laser coding signal repetition frequency and a relatively high distance resolution. A low-speed detector which is adopted effectively reduces the requirement of the system to electronic components. The optical delay which is introduced by the stepping motor eliminates an electronic signal processing step.
