摘要： A laser distance measuring apparatus and control method thereof includes an emitter, a first and second liquid crystal display module, a receiver, a condensing lens, and a control unit. The emitter emits measuring light. The control unit sets the first liquid crystal display module to a second state and the second liquid crystal display module to a first state to receive the reflected light. When the reflected light is larger than a predetermined value, the control unit adjusts a transmittance of the first liquid crystal display module until the reflected light is lower than the predetermined value, and calculates a distance value based on phase difference between the reference light and the reflected light.
