摘要：

By using 2-beam fiber laser doppler velocimeter (ldv), velocity measurement can be conducted by using the offset angle between laser beams. Another unique feature in velocity measurement using 2-beam ldv is the appearance of the third spectrum that can be observed when 2 laser beams irradiate to the same spot on the measurement target. We demonstrated the application of third spectrum frequency to obtain moving object velocity within velocity distribution of liquid flow.
