Abstract: A thermo-optic system, which may be used for example in thermal imaging, includes an array of optical elements each having a thermally responsive optical property, the optical elements including signal elements and reference elements configured to provide (1) a common-mode response of the optical property to ambient temperature and (2) a differential-mode response of the optical property to a thermal signal appearing across the array of optical elements. The system also includes an optical readout subsystem configured to (1) illuminate the array of optical elements with optical energy at a readout wavelength corresponding to the optical property so as to generate a composite optical signal having common-mode and differential-mode signal components corresponding to the common-mode and differential-mode responses respectively of the signal and reference elements, and (2) filter the composite optical signal to generate a filtered optical signal being substantially the differential-mode image component.

Abstract: An apparatus (43) includes a thin-film interference filter structure (10) having a generally wave length- dependent resonant response to incident optical energy in a predetermined range of wavelengths. The thin-film interference filter structure (10) includes a thermally tunable layer (16) having a thermally tunable optical characteristic such that a range of wavelength-dependent resonant optical responses of the thermally tunable layer (16) are induced by a corresponding range of thermal conditions of the thermally tunable layer. The thin-film interference filter structure (10) is configured to (1) receive a spatially varying pattern of thermal energy (51) at the thermally tunable layer (16) to impart a corresponding spatially varying pattern to the thermally tunable characteristic of the thermally tunable layer (16), and (2) receive the incident optical energy (22) into the thermally tunable layer (16) and output optical energy (26) having spatial modulation corresponding to the spatially varying pattern (51) of the thermally turnable characteristic.

Abstract: An IR camera system includes an array of thermally-tunable optical filter pixels, an NIR source and an NIR detector array. The IR camera system further includes IR optics for directing IR radiation from a scene to be imaged onto the array of thermallytunable optical filter pixels and NIR optics for directing NIR light from the NIR source, to the filter pixels and to the NIR detector arrays. The NIR source directs NIR light onto the array of thermally-tunable optical filter pixels. The NIR detector array receives NIR light modified by the array of thermally-tunable optical filter pixels and for produces an electrical signal corresponding to the NIR light the NIR detector array receives. Said thermally-tunable optical filter pixels comprise a thermally tunable thin film interference coating.
