| Abstract/Summary |
We demonstrate accurate, purely optical measurement of optical torques acting on particles composed of either isotropic or birefringent materials. Since the optical torque primarily depends on changes in the spin angular momentum of the light during scattering, the change in the angular momentum, and hence the optical torque, can be determined by measurement of the polarisation of the scattered field.
