When the Bird Daylight Laser 200 emits a powerful green light that hits bird feathers, it makes a bright splash of light. Which traumatizes them and they can't fly away fast enough. A flock of more than 100 geese immediately took flight..
resolution will be in the range of micrometers, but the maximum range is limited to only a few meters. Up to distances of 100m people often use the phase shift measurement. The laser light is modulated and the phaseshift between outgoing and incoming light gives the distance. To reach a resolution in the millimeter range very high sampling rates are necessary. Only low measuring rates with high current consumtion are possible the consequence. With Time-to-Digital-Converters (TDCâs) you choose the straight way. It is possible to measure directly the time-of-flight of light.
