The time-of-flight laser anemometer versus the laser Doppler anemometer
Abstract
A theoretical comparison is made between the laser Doppler anemometer (LDA) and the time-of-flight laser anemometer (TFLA). The TFLA is found to be superior to the LDA in many cases. Three applications are described where the LDA has been inferior to the time-of-flight anemometer; they are: measurements in a two-phase flow around a simulated fuel rod, remote measurement of wind velocity and boundary layer measurements close to a wall.
