We describe a portable astronomical polarimeter system employing a photoelastic modulator and digital synchronous detection to extract simultaneously three of the four Stokes' parameters of the incident light. Light polarization by the telescope optics is the major systematic offset error. A minicomputer is employed for data handling, control, and quick-look Fourier transformation of time-series data.
