LM-0400 Laser Range Finder Set-up
When children are playing while striking the vertical bars of a picket fence with a stick it gives a characteristic burst like noise. The faster they are running the shorter the burst is however the frequency of the strikes is higher. The same principle Yeh and Cummins exploited 1964 when they invented their Laser Doppler Anemometer. Anemos is a Greek word and means “wind”. Consequently a Laser Doppler Anemometer (LDA) can be considered as a “wind meter” using a laser.Item | Code | Qty. | Description |
