Scan Pattern Visualization

Galvanometer Systems

Optical deflection: θ_optical = 2 × θ_mechanical

Advantages:

  • High precision (μrad resolution)
  • Fast response (kHz bandwidth)
  • Large deflection angles
  • Bidirectional scanning

Applications: Laser marking, 3D printing, microscopy

Acousto-Optic Modulators

Bragg angle: θ = λf/(2nv)

Advantages:

  • Very fast switching (ns)
  • No moving parts
  • Simultaneous modulation
  • High reliability

Applications: Q-switching, beam deflection, frequency shifting

Piezo Steering

Displacement: Δl = d₃₃ × V × L

Advantages:

  • Sub-nanometer precision
  • High resolution
  • Low power consumption
  • Stable positioning

Applications: Fine beam alignment, vibration compensation

Polygon Scanners

Scan frequency: f_scan = RPM × N_faces / 60

Advantages:

  • Very high scan rates
  • Constant velocity scanning
  • High duty cycle
  • Large beam diameters

Applications: Laser printing, high-speed marking

⚠️ Beam Steering Safety

Eye Safety: Beam steering systems can redirect laser beams in unexpected directions. Ensure proper beam blocks, safety interlocks, and controlled access areas. High-speed scanning can create apparent continuous exposure even with pulsed lasers. Always consider worst-case beam paths and implement appropriate safety measures for the entire scan range.
