    Abstract: An interferometric sensor (10) employs a sensing optical fiber (12) and a reference optical fiber (14). The sensing fiber (12) has a coating 16 thereon responsive to radiated thermal energy while the reference fiber is shielded therefrom. Both the sensing and reference fibers are subjected to the same ambient environment so that both fibers are subjected to heating by convection or conduction in essentially the same amounts. As a result, the sensor (10) is substantially nonresponsive to convected or conducted thermal energy while being highly responsive to radiated energy, particularly in the 6-30 micron wavelength region.

    Abstract: A semiconductor device for measuring IR radiation comprising: at least one sensor pixel; at least one reference pixel shielded from said IR radiation comprising a heater; a controller adapted for: measuring a responsivity by applying power to the heater, while not heating the sensor pixel; measuring a first output signal of an unheated pixel and a first reference output signal of the heated pixel, obtaining the responsivity as a function of a measure of the applied power to the heater and of the difference between the first output signal and the first reference output signal; applying a period of cooling down until the temperature of the reference pixel and the sensor pixel are substantially the same; generating the output signal indicative of the IR radiation, based on the difference between the sensor and the reference output signal, by converting this difference using the responsivity.

    Abstract: An infrared sensor assembly for sensing infrared radiation from an object is disclosed. The infrared sensor assembly comprises a sensor array comprising a plurality of sensing elements, provided on or embedded in a substrate extending in a substrate plane. The sensor array comprises at least two infrared sensing elements, each infrared sensing element having a radiation responsive element providing a proportionate electrical signal in response to infrared radiation incident thereto and at least two blind sensing elements, at least one blind sensing element being interspersed among the at least two sensing elements, each blind sensing element being shielded from incident infrared radiation from the object and providing a proportionate electrical signal in response to parasitic thermal fluxes. The output of the sensor array is a function of the infrared sensing elements and of the blind sensing elements such that parasitic thermal fluxes are at least partly compensated for.

    Abstract: The invention relates to a passive microbolometer (12), comprising a reflective screen (17) and a suspended membrane with the function of radiation absorber, thermometer and electrical connection. The membrane is supported by at least two anchor elements (15) fixed to a support substrate (16). The reflective screen (17) may be embodied by at least one layer (18) of metallic material with a thickness of the order of 500 Å to 2000 Å. The screen (17) is arranged beneath the membrane in electrical contact with the membrane absorber element (13) such as to reduce the area resistance of the unit made up of the screen (17) and the absorbing element (13) and to avoid the absorption of radiation by the latter.
