Abstract (en)
[origin: WO0072079A2] An electro-optic device includes a polarising beam splitter (1) wihch sends a polarised component along a first path via birefringent cells (C1 and C2) and a differently polarised component via a second path through cells (C3 and C4). The two components are combined at 8 and the output directed onto a CCD sensor (9). The modulator has high transmission characteristic and allows faster switching. In one embodiment, the device is used to view differently polarised light from a scene.
