…and laser projector on the same side of the normal to the object surface. This dramatically reduces the
chance of specular reflections, unless the object is highly
textured. It works best with highly reflective objects.
This configuration also substantially reduces height resolution…

…a object. Some of this light is reflected or scattered back to the instrument where it is analyzed. The changes in the light enables some properties of the object to be determined. The time for the light to travel out to the object and back to the LIDAR is used to determine the range to the object.

…At present, the most popular of these techniques all rely on laser illumination of fluorescently tagged bases. The diversity of methodology is reflected in the diversity of laser parameters needed for the different approaches. Some utilize tight focus and use just a few tens of milliwatts, whereas…

…hazard for back reflections. Change the objects to be less reflective whenever
possible. Adding Anti-Reflective (AR) coatings to optics and more diffuse
surfaces to mounts or beam shutters can help.

· Watch where the reflections from objects are returning to make sure the reflections
are not at or near the laser exit aperture. Change the objects to add an angle so the
object is less reflective whenever possible. Add an optical isolator to those…

…for planar objects. The Specular geometry may be preferred where height resolution is a
primary consideration or where low object reflectivity (i.e., image brightness) is an issue. And
conversely, the Look-Away arrangement is sometimes used where high object reflectivity is a challenge.…

these reflections produce saturation or blooming in the detector. On the other hand, higher
reflection could be used to increase signal
levels from dark colored objects since dark
