Paper Abstract

Several designs that could produce significant wavelength selectivity in micromachined microbolometers are reviewed. These frequency selective surfaces can be achieved using stacks of dielectric coated resistive sheets or by replacing the normal uniform absorbing sheet used in IR microbolometers with true microbolometers (i.e., bolometers that are much smaller than the wavelength) combined with an antenna. Here we discuss dielectric coated designs that can substantially improve the wavelength selectivity of microbolometers.
