Electronic Distance Measuring Instruments01:30

Electronic Distance Measuring Instruments

Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over short distances...

    Area of Science:

    • Optics and Photonics
    • Sensing Technologies
    • Signal Processing

    Background:

    • Frequency Modulated Continuous-Wave (FMCW) Light Detection and Ranging (LiDAR) offers high range resolution but struggles with large data volumes in long-range applications.
    • The de-chirping receiving principle in traditional FMCW LiDAR contributes to high data rates, limiting its efficiency for extended detections.

    Purpose of the Study:

    • To develop a data-compressed FMCW LiDAR system capable of long-range and high-resolution detection.
    • To overcome the limitations of large data volumes and high bandwidth requirements in conventional FMCW LiDAR systems.

    Main Methods:

    • Proposed a novel receiving method utilizing a time-frequency optical comb (TFOC) instead of a traditional single linear frequency modulating (LFM) reference signal.
    • The TFOC enables echoes to beat with the nearest LFM comb tooth, decoupling target range from beating frequency.

    Main Results:

    • Achieved a resolution of less than 1.87 cm for targets across multiple ranges (0.11-0.50 m, 0.38-179 m, and 1.5-5.2 km).
    • Demonstrated the system's capability with a reduced receiver bandwidth of 125 MHz for an 8 GHz sweeping bandwidth, yielding a data compression ratio of 64.
    • Significantly decreased beating frequency, receiver bandwidth, and data volume compared to conventional methods.

    Conclusions:

    • The proposed TFOC-based FMCW LiDAR significantly reduces data volume and bandwidth demands.
    • This advancement lowers the requirements for high-bandwidth photodetectors, memory, and processors in FMCW LiDAR systems.
    • Enables more efficient and practical long-range, high-resolution LiDAR applications.
