The invention relates to a self-lubricating bearing coating thickness detection system and method based on optical coherence tomography, and the system comprises a tungsten halogen lamp light source module which is used for transmitting a light beam; the first convex lens is used for collimating emitted light of the tungsten halogen lamp light source module into parallel light beams; the Michelson interferometer module is used for splitting the light beam into two beams of light with the same intensity, the two beams of light serve as reference light and probe light to be converged on a reference mirror and the surface of a bearing coating to be detected respectively, the two beams of light coincide after being reflected to generate interference, and interference light beams are formed; the two-dimensional spectrometer module comprises a reflecting mirror, a reflective grating, a cylindrical lens and an area array CCD camera, the interference light beams are transmitted to the reflective grating through the r
