Abstract
A device for variable polarization by an illumination device for illuminating organic tissue. The device includes a first set of one or more light emitting diodes (LEDs), a first polarizer arranged to polarize light emitted from the first set of LEDs in a first polarization direction, a second set of one or more LEDs, a second polarizer arranged to polarize light emitted from the second set of LEDs in a second polarization direction. A lens is arranged to collect light from organic tissue illuminated by the first and/or second sets of LEDs including a viewing polarizer arranged to polarize the light collected from the organic tissue in the second polarization direction. A signal generator is operable to signal one or more drivers for driving one of the first and second sets according a signal value and driving the other of the first and second sets according to an inverse value thereof.
