title: Note: digital optical zoom by selection of polarization.
abstract: The combination of a liquid crystal cell with a polarizing beam splitter is used to select one of the two paths through an optical imaging system. The paths both focus the same image on a CCD detector, but one has 4 times the magnification of the other.
