Abstract
In this paper, we present a self-mixing double-head laser diode velocimeter. Several analyzes are performed to determine the optimal architecture of the double laser diode in terms of accuracy. We demonstrate that the double-head laser diode is insensitive to angle variation contrary to the single laser diode. The accuracy of the double-head laser diode sensor is verified by simulations and experiments.
