ELECTROWETTING OPTICAL DEVICE

Abstract:

A selective optical shutter can include a first window, a second window, and a cavity disposed between the first window and the second window. A filter can be disposed in an optical path of the optical shutter, whereby the filter blocks of one of ultraviolet (UV) light or infrared (IR) light and passes each of visible light and the other of UV light or IR light. A first liquid and a second liquid can be disposed within the cavity. The first liquid and the second liquid can be substantially immiscible with each other, whereby a liquid interface is formed between the first liquid and the second liquid. The liquid interface can be adjustable by electrowetting to selectively pass visible light or the other of UV light or IR light.
