PURPOSE: A stability measuring system for a multi-stepped light receiving optical rotator which has a sensor are provided to recover the stability in case of unbalance rotation after complete assembling of the rotator, without any disassembling of the rotator, and precisely calculate the mass and position of a disc of the rotator with respect to any additional mass. CONSTITUTION: A stability measuring system for a multi-stepped light receiving optical rotator which has a sensor includes a light source(300) for generating parallel light, a rotator(310) for receiving the parallel light, a rotation supporting part(320) fixing the rotator via a rotation bearing, a spin-up unit(330) for rotating the rotator and controlling the rotation velocity of the rotator, a sensor(340) for sensing signal reflected against the rotator, a signal amplifier(350) for amplifying the signal received from the sensor, and a signal comparison/computation processor(360) for storing the amplified signal and comparing/computing a value of the signal. |
