    Abstract: Methods and apparatus are provided to determine the emissivity, temperature and area of an object. The methods and apparatus are designed such that the emissivity and area of the object may be separately determined as functions dependent upon the temperature of the object derived from a three or more band infrared measurement sensor. As such, the methods and apparatus may only require a regression analysis of the temperature of the object without any regression analysis of the emissivity and area of the object.

    Abstract: A method for correction of non-uniformity in signal level in different image points in an IR-camera, based on a scene being observed during movement in time of detector elements, of a camera in which the detector elements are arranged and/or of the scene, with deviating output signals for the same energy in the scene measured by different detector elements being corrected for image interference so that they provide essentially the same output signal. Micro-mechanical gyros are introduced that measure the angular velocity parallel to and perpendicular to the optical axis of the scene. The measured movement is used as an estimate for calculating the movement with a movement estimation method based on scene data. The estimated movement is coordinated with an associated image. The difference between the most recent image and the immediately preceding image or the average value of a plurality of preceding images is calculated as offset parameters. The offset parameters are updated by correction of previous offset parameters with the most recent offset parameters. The most recent image is corrected for static noise by applying the most recently produced offset parameters to the most recent image.

    Abstract: An optical system measures scene inhomogeneity. The system includes a mirror for receiving radiance of a field-of-view (FOV) of a scene, and reflecting a portion of the radiance to an optical detector. A controller is coupled to the mirror for changing the FOV. The optical detector provides a signal of the reflected portion of radiance of the scene. A processor determines scene inhomogeneity, based on amplitude of the signal provided from the optical detector. The controller is configured to modulate the FOV at a periodic interval, using a sinusoidal waveform, a pulse code modulated waveform, or a pseudo-random waveform.

    Abstract: A radiation sensor includes an integrated circuit radiation sensor chip (1A) including first (7) and second (8) thermopile junctions connected in series to form a thermopile (7,8) within a dielectric stack (3). The first thermopile junction (7) is insulated from a substrate (2) of the chip. A resistive heater (6) in the dielectric stack for heating the first thermopile junction is coupled to a calibration circuit (67) for calibrating responsivity of the thermopile (7,8). The calibration circuit causes a current flow in the heater and multiplies the current by a resulting voltage across the heater to determine power dissipation. A resulting thermoelectric voltage (Vout) of the thermopile (7,8) is divided by the power to provide the responsivity of the sensor.

    Abstract: An infrared imaging system having functionality for maintaining image quality in the presence of temperature drift of the system. Such functionality is applied repetitively to maintain image quality of a target scene, yet without continuous actuation of a shutter of the system. The functionality of the imaging system results from implementing an imager algorithm. In use, the imager algorithm functions with a calibration curve created for the imaging system, with the curve comprising a plot of system output versus target scene temperature.
