Beschreibung
Zusammenfassung:	The specification discloses an automated optical instrument system which includes a support pedestal rotatably supporting a housing on the upper end thereof. The housing includes a laser for directing a collimated beam of light for use in surveying and also includes an infrared detector system mounted therein. A portable beacon which emits infrared waves is adapted to be attached to a surveying stadia rod or to earth moving equipment or the like. The infrared detector system detects the position of the beacon and operates a motor to pivot the housing such that the laser beam is continuously maintained in alignment with the stadia rod. In case the path between the beacon and the infrared detector system is interrupted, circuitry is provided to continuously cycle the housing until the beacon is again sensed by the infrared detector system.
