    Abstract: A hyperspectral imaging system has a processor to receive hyperspectral imaging parameters and produce a series of images to be acquired at a series of retardances at a series of retardance times, a hyperspectral imaging component having an input polarizer to polarize an incoming beam of light, a liquid crystal variable retarder to receive the polarized beam of light and to produce wavelength-dependent polarized light, an output polarizer to receive the wavelength-dependent polarized light and to convert polarization state information into a form detectable as light intensity, a voltage source connected to the liquid crystal variable retarder, and a retardance controller. The retardance controller receives the series of retardances at a series of retardance times and produces a series of voltages at a series of voltage times to apply to the liquid crystal variable retarder. A focal plane array, synchronized with the retardance controller, receives the light in a form detectable as light intensity and converts the light to a series of images.
