Abstract: Methods and apparatus for preventing solar damage, and other heat-related damage, to uncooled microbolometer pixels. In certain examples, at least some of the pixels of an uncooled microbolometer are configured with a bimetallic thermal shorting structure that protects the pixel(s) from excessive heat damage. In other examples a thermochroic membrane that becomes highly reflective at temperatures above a certain threshold is applied over the microbolometer pixels to prevent the pixels from being damaged by excessive heat.
