| 摘要 | A fibre-fixing arrangement (4, Fig 2) consists of a plane parallel plate (42) having at least two recesses (43) in pairs symmetrically with respect to an optical axis predetermined by a transmitting optical device (71) in order to receive the transmitting fibres (31) fixed orthogonally in the plate (42), the end surfaces of the transmitting fibres (31) coinciding with the plane of connection (45, Fig 2) which is adjoined by a rigidly coupled lens array (5, Fig 2), and the lens array consists of a plane parallel supporting plate (52) with collimating lenses (51) attached by cementing, wherein the number and position of collimating lenses (51) corresponds to the number and position of the transmitting fibres (31) and the parameters of the subsequent transmitting optical device (71), and the optical path length as far as the collimating lens (51); is adapted by adjustment of the thickness of the supporting plate (52) to the aperture of the transmitting fibres (31) and the focal length of the transmitting optical device (71) so that the laser narrowings of the transmitting beam (6) focused through the transmitting optical device (71) coincide upon superimposition in a volume for measurement (8) in a laser Doppler measuring device eg. an anemometer. |
| 其他摘要 | 光纤固定装置（4，图2）由平面平行板（42）组成，平面平行板（42）具有至少两个凹槽（43），这些凹槽（43）相对于由发射光学装置（71）预定的光轴对称，以便接收传输光纤（31）正交地固定在板（42）中，传输光纤（31）的端面与连接平面（45，图2）重合，连接平面与刚性耦合的透镜阵列（5，图2）相连如图2所示，透镜阵列由平面平行支撑板（52）和准直透镜（51）组成，其中准直透镜（51）通过粘合连接，其中准直透镜（51）的数量和位置对应于透射光纤（31）的数量和位置。 ）和后续发送光学装置（71）的参数，以及光路长度到准直透镜（51）;通过调节支撑板（52）的厚度到发射光纤（31）的孔径和发射光学装置（71）的焦距来调整，使得发射光束（6）的激光变窄通过发射光学装置（71）在激光多普勒测量装置中叠加在测量体积（8）中时重合。风速计。 |
