Publishes papers reporting on research and development in optical science and engineering and the practical applications of known optical science, engineering, and technology.It is also caused by the release of the resistant torque stress when the actuator motor begins to inversely rotate in ... The resistant torque stress differs considerably in different actuators, and that makes the shape of the spot diagram irregular. ... Appl.
