| description | Apparatus for laser anemometry comprises a device for producing coherent radiation, a beam splitter device adapted to divide the beam from this device into two beam portions, focussing means adapted to focus these two beam portions on to two adjacent spots, and two photodetector means each adapted to measure the scattered illumination from one said spot. In order to enable the direction of the path between the two spots to be altered without moving the entire apparatus, an image rotation device is provided and mounted to effect both the beam portions and the scattered radiation from the spots which falls on the photo-detector means. |
