Nondiffracting beam based technology for an attitude measurement system for automatic orientation of shield

Abstract. An electronic target technology based on a nondiffracting beam for spatial attitude determination is proposed. Automatic orientation of shield tunnel equipment is achieved by a spatial-coordinates measurement system consisting of an electronic target and a total station. During the measurement, a ranging laser beam is sent from the total station. It is transformed into a nondiffracting beam by an axicon, and the beam spot images are captured by a charged-coupled device image sensor. Since the center of the nondiffracting beam has a one-to-one mapping to the incident direction of the laser, the spatial orientation of the laser beam can be obtained via center fitting of the nondiffracting images. When this system is combined with a two-dimensional electronic inclinometer, the attitude parameters can be determined from the relationship of different spatial angles. Experimental results demonstrate that the attitude measurement system has a precision of ±0.5  mrad. Further, the engineering applications also show that the system has high operational quality and environmental adaptability.
