The developed laboratory LDA system is operated at the one-color dual-beam mode with the confocal annular detection and polarizational separation of the backscattered Doppler signal, allowing for the measurements of the axial or tangential velocity components up to 600 m/s in the absolute coordinates. Doppler signals between the blade passages are gated and evaluated by a counter. The operation of the system will be illustrated by measurements of the axial flow field velocity component at the impeller of a research turbocharger.
