| Abstract: | We describe a new LDV system which can simultaneously measure velocities at different points in a velocity field. The measurement system features a simple structure,high accuracy and fast frequency response, The structure of the proposed system and the principle of the operations are described in detail. A theoretical analysis on Doppler shifts in the system is presented. Experiments to demonstrate the developed LDV system are also described. |
