Abstract

In modern science and technology, LiDAR plays a key role in automatic navigation, industrial mapping and other fields, but the traditional phase ranging system has many problems such as low measurement accuracy and complex structure. A new high-precision phase laser radar ranging system is proposed in this paper. The system adopts the phase difference detection method of laser control with the same frequency reference, including the optical structure optimization of the laser transmitting and receiving modules, and the amplification filtering and differential mixing processing of the receiving circuit, and finally produces a high-resolution phase discrimination system based on AD8302. The experimental results show that the measurement accuracy of the system is millimeter level, which is simple and practical and can meet the needs of a wide range of practical applications. This research provides a feasible solution for LiDAR technology in high-precision distance measurement.

Overview

Overview

With the advent of the intelligent era, laser ranging is widely used in remote sensing, and the development and research of radar technology has been attached to great importance in the world. Phase ranging is one of the most favourite ranging ways at present, and the phase LiDAR ranging technology has a wide application prospect in modern science and technology, especially in the fields of automatic driving, robot navigation, three-dimensional mapping and so on. Compared with traditional ranging methods, phase LiDAR ranging technology can achieve higher accuracy and resolution. However, despite significant progress in phase LiDAR ranging technology, there are still some not solved troubles. For example, the measurement accuracy and performance stability problems in complex environments, and the cost of high-precision phase ranging systems is usually higher, which restricts its widespread application in certain fields. The objective of this study is to design and develop a high-precision phase LiDAR ranging system. To improve the measurement accuracy and stability of phase ranging and reduce the cost of the laser ranging system. Firstly, Based on the principle of phase laser ranging, the transmitting and receiving parts of the optical system are designed and selected to ensure the stable transmission and reception of the laser. Then the receiver circuit of the hardware system is processed with signal amplification, filtering and mixing structure. In the case of large high-frequency phase discrimination errors, the method of mixed-frequency phase identification is used to improve the accuracy of the system. Finally, The AD8302 module is used as a foundation to improve the measurement accuracy of the system, simplify the hardware design of the system, and reduce the need for traditional complex signal processing algorithms. At the same instant, the technology of multi-ruler joint measurement is adopted. The high precision advantage of high frequency is used to improve the accuracy of the measured distance, and the wide range advantage of low frequency is used to expand the range of the measured distance to meet the long-distance requirements of high precision. Through the performance evaluation of the system, the system meets the design requirements. The experimental result manifests that the measurement system not only has high measurement accuracy and strong stability, but also reduces the complexity and cost of the system and meets the practical application requirements.
