Beam Resizing Optics

When the laser beam is larger than the camera sensor, or smaller than a few camera pixels
When the laser beam is larger than the camera sensor, or smaller than a few camera pixels, techniques are available to properly adjust the beam size.

  • Beam expanding telescopes are commercially available that resize the beam with little or no distortion to the beam profile.
    • A telescope can be used in either direction to reduce or enlarge the beam width.
  • When beams are too large for a telescope, then they can be reflected from a scattering surface, and the reflection imaged onto the camera with a normal camera lens.
    • Depending on the wavelength the scattering surface may need to be physically in motion during the measurement to reduce speckle.
