A method for measuring the absolute throughput of a polarization modulating reflective display in an optical system having a folded light path. The steps include measuring a first light intensity, LR, in the folded light path, having a first polarizing beam splitter, and a reflective display. A second intensity, LO, is measured using an unfolded light path where the reflective display is replaced by a second cross-rotated polarizing beam splitter. The absolute throughput is TM is calculated, where TM=LR/LO.
