Polarization adjustment strategies.

	Design features	Integration issues	Imaging issues
Rotating polarizer	Simple and robust; Time consuming; Suitable for static scenes	Inexpensive; Easy to implement	Misregistration; Low efficiency
Beam splitter	Large size; Light splitting; Simultaneous acquisition	Expensive; Complex integration; High mechanical flexibility	Easy to align; High efficiency; Low contrast
Division of aperture	Small size; Simultaneous acquisition	Expensive; Complex optical elements	Easy to align; Low spatial resolution
Division of FPA	Small size; Compact; Simultaneous acquisition	Expensive; Complex fabrication; High mechanical flexibility	High efficiency; Imaging blur; Low spatial resolution
