Abstract

A device for leveling a laser transmitter is provided. An optical position sensor is used to measure the position of a compensator assembly. The compensator assembly automatically adjusts the position of the laser beam once the compensator assembly is within a specified range of level. Once the compensator assembly is within the specified range, the compensator assembly optically adjusts the laser beam so that it is plumb. A leveling device may be used to level the laser transmitter in response to the position of the compensator assembly as measured by the position sensor.
