Abstract: A method for dynamically calibrating automatic infrared sensing devices in commercial use having an IR detector. Randomly reflected emitted IR radiation is detected by the IR detector which sends as IR detector output to a control module. The control module measures whether the detector output is too high or too low compared to a standard range of output values stored in the control module. An IR emitter value is then determined to maintain IR detector output within the standard range of values. This IR emitter input value is stored in the control module as a calibration standard until the calibration cycle.

Abstract: An infrared image-processing apparatus capable of binarization processing in response to the change of the brightness histogram includes an image-processing unit which executes a binarization processing for an infrared image using a threshold brightness value determined in a previous processing, and calculates an area ratio P. When the binarization area ratio P is below a prescribed value &agr; (%), and if the threshold brightness value is not the minimum threshold brightness value Mm_TH, the threshold brightness value ITH is reduced by subtracting a predetermined ratio. Similarly, when the binarization area ratio P is above predetermined value &bgr; (%), and the threshold brightness value is not the maximum threshold brightness value Max_TH, the threshold brightness value is increased by incrementing a prescribed value to the threshold brightness value ITH.

Abstract: An apparatus for detecting a gas having distinct infrared radiation absorption characteristics. The apparatus includes a spectral source/bolometer for conducting an electrical current and for producing an infrared radiation. The source/bolometer is disposed along an axis and has a temperature and a characteristic resistance, and the characteristic resistance is a predetermined function of the temperature. A return reflector is disposed along the axis beyond the gas such that at least a portion of the infrared radiation passing through the gas is reflected back through the gas to the source/bolometer. The apparatus also includes a driver/detector for driving a current through the source/bolometer, for determining the characteristic resistance, and for detecting the gas from a variation of the characteristic resistance.

Abstract: Methods and apparatus for compensating a radiation sensor for ambient temperature variations. Ambient temperature variations may produce undesirable artifacts in electronic signals output by a radiation sensor. In some cases, such artifacts may detrimentally reduce the dynamic range of the sensor and/or processing circuitry associated with the sensor with respect to radiation of interest. The radiation sensor may be compensated for such undesirable artifacts by, for example, adding an appropriate offset to a sensor bias voltage or a sensor bias current, and/or controlling a temperature of the radiation sensor, based on variations in the ambient temperature.
