ABSTRACT:
An IR limiting device for a detector that is based on a micro-optomechanical cantilever array is disclosed. In the normal state, each microcantilever device in the array behaves like a mirror that reflects the infrared signal to the detector. The microcantilever device absorbs radiation outside the desired infrared region. When the radiation is stronger than a predetermined threshold, the microcantilever device bends as a result of thermo-mechanical forces, and it reflects the signal away from the detector, thereby limiting the radiation. The advantage of such a system is that each pixel in the detector can be addressed individually, and the limiting is localized.
