In this study, the velocity profile acquisition technique based on laser Doppler velocimetry, which have a variable-focal system was proposed. As the variable-focal system, the focus tunable lens was installed in the transmitting optics. The proposed technique provided us that it became possible to obtain the velocity profile for axial direction without any mechanical scanning systems. The velocity profile in a parallel plate channel was measured to demonstrate the proposed technique. The calibration procedure of the technique and its validity were also described.
