Abstract
A thermal detector having an optical coating comprising a porous film 64. The porous film preferably comprises a xerogel or aerogel and is greater than 80% porous. An optional optical impedance matching layer 66 may be deposited over the porous film 64. Advantages include decreased thickness of the thermal sensor, improved acuity of the image produced by the system, lower manufacturing temperatures, and the ability to use electrodes that are opaque to infrared energy.
