Abstract
AbstractThe laser technique based sensors and actuators can provide many superior properties as noncontact, high sensitivity, remote operation, and reliable performance in contrast to other mechanical and electrical techniques. In this paper, we design and fabricate a high‐precision 360° laser receiver for leveling, especially for agricultural and construction field. The laser receiver is primarily composed of photoelectrical conversion module, electrical signal processing module, and display panel module. Based on the centroid method, the detection error of the laser receiver with respect to laser source and silicon photocell array, is analyzed and simulated. The design and fabrication process are described in detail, including the overall structure and electrical circuits. Furthermore, this fabricated laser receiver is demonstrated to be high precision through several static and dynamic tests in the distance of 10 and 50 m. Besides, this fabricated laser possesses wireless transmission function, which provides much convenient for users in remote operation.
