Abstract
Methods and apparatus for preventing solar damage, and other heat-related damage, to uncooled microbolometer pixels. In certain examples, a thermochroic membrane that becomes highly reflective at temperatures above a certain threshold is applied over at least some of the microbolometer pixels to prevent the pixels from being damaged by excessive heat.
