An Instrument for the Measurement of Electric Dichroism

Abstract

We have constructed an instrument for the measurement of electric dichroism. Through the use of photoelastic modulators we are able to shift the plane of polarization from parallel to the applied electric field to perpendicular, at a cyclic rate of 100 KHz-1 MHz. When an electric pulse is applied to a sample and dichroism arises, an A.C. component appears in the output of the photomultiplier tube. We have devised a digital procedure which is analogous to a lock-in amplifier for processing this A.C. signal.
