Simultaneous Measurement of Dichroism and Birefringence on Suspensions of Absorbing Particles

  • J. C. Ravey
  • C. Houssier

Abstract

The principle of a new method for the simultaneous measurement of the dichroism and birefringence (including the determination of their signs) of absorbing solutions subjected to electric pulses, is described. It involves the measurement of the photocurrent signals as a function of the angle of the polarization directions with respect to the electric field. Observations on carbon-black suspensions using this procedure are reported.
