A laser distance measuring system includes an object lens, a beam splitter, a transmitter, a receiver, and a shutter mechanism. The beam splitter is disposed at one side of the object lens. The transmitter emits a laser beam that is split by the beam splitter into a measurement beam and a reference beam. The measurement beam passes through the object lens, and is reflected by an object to result in a reflected measurement beam passing through the object lens. The receiver is disposed to receive the reflected measurement beam and the reference beam. The shutter mechanism includes a beam masker operable to move to either block path of the reflected measurement beam to the receiver or path of the reference beam to the receiver.
