Embodiments of the disclosure provide a Light Detection and Ranging system. The system may include a light source configured to emit a light beam, a first apparatus configured to adjust the light beam and a second apparatus configured to adjust the light beam and receive the reflected light beam from a first rotatable mirror. The first apparatus may include the first rotatable mirror configured to receive and reflect the light beam, and a first actuator configured to rotate the first rotatable mirror. The second apparatus may include a second adjustable mirror configured to receive and propagate the light beam, a second actuator configured to adjust the second adjustable mirror, and a detector configured to receive the light beam reflected by the object. The first rotatable mirror is further configured to receive and reflect the light beam reflected by the object to the detector.
