We propose a multi-terminal(Non-magnetic) mesoscopic electrical transport measurement for measuring Rashba spin orbit strength. The method proposed is different from the usual magneto transport measurements, which require magnetic fields for e.g. Shubnikov-de Hass oscillations or weak anti-localization measurements. Our methods uses three terminal mesoscopic device, in which one of the terminal acts as a voltage probe. We show that the Voltage measured at the non-magnetic voltage probe depends on the strength of Rashba spin-orbit interaction.
