A simple technique is described for determining the polarization of He(2{sup 3}{ital S}) atoms contained in an active discharge or afterglow. The polarization (and alignment) is obtained by measuring the attenuation of a circularly polarized probe beam provided by a 1.083 {mu}m laser diode whose output frequency is scanned to allow separate measurements on the 2{sup 3}{ital S}{sub 1}{r_arrow}2{sup 3}{ital P}{sub 0}, 2{sup 3}{ital S}{sub 1}{r_arrow}2{sup 3}{ital P}{sub 1}, and 2{sup 3}{ital S}{sub 1}{r_arrow}2{sup 3}{ital P}{sub 2} transitions. {copyright} {ital 1996 American Institute of Physics.}
