提出了一种采用48通道空间编码测量点的差分激光多普勒测速仪，用于测量密集截面的速度分布。采用非对称推挽结构和多个光电二极管来增加测量点的数量。实验证明了所提出的结构的功能。结果表明，成功地测量了横截面的速度分布与建议的结构。
A differential laser Doppler velocimeter using 48-channel spatial encoded measurement points is proposed for dense cross-sectional velocity distribution measurements. An asymmetrical push-pull configuration and multiple photodiodes are employed to increase the number of the measurement points. The functionality of the proposed structure is experimentally demonstrated. The results indicate that a cross-sectional velocity distribution is successfully measured with the proposed structure.
