摘要： A fluid analyzer includes an optical source and an optical detector defining an optical beam path through an interrogation region of a fluid flow cell. Flow-control devices conduct analyte and reference fluids through a channel and the interrogation region, and manipulate fluid flow in response to control signals to move a fluid boundary separating the analyte and reference fluids across the interrogation region. A controller generates control signals to (1) cause the fluid boundary to be moved across the interrogation region accordingly, (2) sample an output signal from the optical detector at a first interval during which the interrogation region contains more analyte fluid than reference fluid and at a second interval during which the interrogation region contains more reference fluid than analyte fluid, and (3) determine from samples of the output signal a measurement value indicative of an optically measured characteristic of the analyte fluid.

摘要： 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.

摘要： A tunable laser has a solid state laser medium having an optical gain region and generates coherent radiation through a facet. A lens collects the coherent radiation and generates a collimated light beam. Components of an external cavity include a reflective surface and an optical filter, the reflective surface reflecting the collimated beam back to the lens and the laser medium, the optical filter positioned between the reflective surface and the lens and having two surfaces with a thermally tunable optical transmission band within the optical gain region of the laser medium. The optical filter (1) transmits a predominant portion of the collimated beam at a desired wavelength of operation, and (2) specularly reflects a remaining portion of the collimated beam from each surface, the collimated beam being incident on the optical filter such that the reflected collimated beams propagate at a non-zero angle with respect to the incident collimated beam.

摘要： 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.
