ABSTRACT:
An infrared detector device is described. It is based on an infrared analog of the Fabry Perot interferometer, using one curved, fully reflecting, plate and one planar, mainly reflecting, but partially transmitting, plate. The space between these plates behaves as a resonant cavity which can be built to respond to either a broad or a narrow band of wavelengths in the general range between 1 and 15 microns. It is also possible to combine several detectors of different narrow bands in a single device. Actual detection of the radiation is based on use of thin film resistors, having a high thermal coefficient of resistance, that are thermally isolated from the other parts of the structure. Details relating to the manufacture of the devices are given.
