Leveling Equipment01:18

Leveling Equipment

As leveling involves measuring vertical distances relative to a horizontal line of sight, it requires a graduated rod, called a level rod, for vertical measurements and an instrument called a level for a horizontal sight line. A level includes a high-powered telescope with a mechanism for leveling to ensure the line of sight is horizontal when the bubble in the spirit level is centered. Leveling rods, made of wood, metal, or fiberglass, are graduated in feet or meters and commonly used in two-...
Influence of Earth's Curvature and Atmospheric Refraction on Leveling01:26

Influence of Earth's Curvature and Atmospheric Refraction on Leveling

During leveling, the Earth's curvature and atmospheric refraction introduce deviations in the line of sight from a true horizontal reference. When the line of sight is leveled, it remains perpendicular to the plumb line only at a single point. Beyond this, it deviates due to the Earth’s curvature, represented by the correction C. For a sight distance D, the deviation can be derived using the relationship:This relationship shows that the deviation increases quadratically with distance. Over a...

Area of Science:

  • Optics and Photonics
  • Metasurface Technology
  • Optical Engineering

Background:

  • Compact light detection and ranging (LiDAR) systems face challenges in balancing field of view (FOV) and signal reception with size constraints.
  • Existing LiDAR receivers often have limited FOV, restricting their applicability in dynamic environments and on platforms like UAVs.
  • Metasurfaces offer potential for novel optical component design due to their subwavelength structure and ability to manipulate light.

Purpose of the Study:

  • To propose a general design principle for metasurface-based light receivers with enhanced large FOV capabilities.
  • To demonstrate a proof-of-concept metasurface device for compact, off-axis LiDAR applications.
  • To improve the effective signal reception and power enhancement in LiDAR systems.

Main Methods:

  • A metasurface-based light receiver was designed using mapping relations for optimal performance.
  • A 20-mm-diameter, 4-region metasurface device was fabricated using deep ultraviolet (DUV) projection stepper lithography.
  • The device was coupled with a 3-mm-diameter avalanche photodiode (APD) for performance evaluation.

Main Results:

  • The metasurface light receiver achieved a large field of view of ±30°.
  • A significant power enhancement factor ranging from 1.5 to 3 times was observed at 940 nm.
  • The device demonstrated effective performance when integrated with an avalanche photodiode.

Conclusions:

  • The developed metasurface light receiver offers a new paradigm for compact, high-performance LiDAR systems.
  • This technology enables enhanced capabilities for applications requiring wide FOV and efficient light reception.
  • The findings support the deployment of advanced LiDAR in fields like unmanned aerial vehicles (UAVs) and miniaturized robotics.
