Abstract: A self-leveling laser transmitter is provided. The laser transmitter comprises a rotation head and an accelerometer mounted on the rotation head. An acceleration signal is received from the accelerometer and one or more tilt adjustment signals for adjusting a tilt of the rotation head to a leveled orientation are generated based on the acceleration signal. One or more actuators adjust the tilt of the rotation head based on the one or more tilt adjustment signals.

Abstract: A laser measuring system comprising a laser transmitter and a laser receiver is provided. The laser transmitter includes one or more laser sources for projecting an initial laser pulse and a reflective surface. The laser receiver includes a first reflective surface for reflecting the initial laser pulse to provide a first reflected laser pulse, and a second reflective surface for reflecting the initial laser pulse to provide a second reflected laser pulse. The laser receiver further includes a photo detection unit for receiving 1) a first double reflected laser pulse produced by the first reflected laser pulse reflecting off the reflective surface of the laser transmitter, and 2) a second double reflected laser pulse produced by the second reflected laser pulse reflecting off the reflective surface of the laser transmitter. The laser receiver determines an orientation angle associated with the laser receiver based on the first and second double reflected laser pulse.

Abstract: A laser measuring system including first and second laser base stations and a laser receiver is provided. The laser receiver detects a first laser signal from the first laser base station. Location information associated with the first laser base station is extracted from the detected first laser signal. The laser receiver detects a second laser signal from the second laser base station. Location information associated with the second laser base station is extracted from the detected second laser signal. A position of the laser receiver is determined based on the extracted location information associated with the first laser base station and the extracted location information associated with the second laser base station.
