For the stability test requirements of precision optical tracking system ,we presented a dynamic testing method of stability accuracy .According to the optical auto‐collimation prin‐ciple ,we utilized the CCD array detector combined with the computation for center of image to realize the dynamic test ,and we required the test results of stability accuracy by this device . Experiments results show that for the 50 μrad level two‐axis two‐frame system ,the tested sta‐bility accuracy is up to 48 μrad by our method .
