Abstract: An infrared radiation detector includes a bolometer or micro-cantilever detector device which functions as a null detector in conjunction with electronic circuitry. The electronic circuitry senses a change in an output signal of the detector as the detector responds to infrared radiation incident upon the detector and provides a signal to a control element which provides a stimulus to the detector device to maintain the detector output signal at the same level. The element may be a piezoelectric element, a heater or a pair of electrodes and the corresponding stimulus may be stress, heat, or electrostatic change. The stimulus compensates for the effect of the infrared radiation and maintains the chosen detector output level at the same level. The nulling circuitry improves the linearity and dynamic range of the detector device.

Abstract: A pyroelectric detector circuit comprises a pyroelectric sensor element connected to a load resistor and to an input of a buffer amplifier having a feedback path for multiplying the resistance of the load resistor at non-zero frequencies. This feedback enables the use of a smaller load resistor which is multiplied to produce a higher effective load resistance necessary for proper low frequency response of the detector circuit.

Abstract: An outdoor light using a motion sensor that activates the light when motion is sensed by changes in the infrared signal detected. The device uses a passive infrared detector network to sense infrared and to produce an analog signal in response to said infrared detected which is then passed through an amplifier to a signal controlled oscillator. The signal is converted into a digital signal which is used to detect motion by a logic device.

Abstract: An infrared photo-detector focal plane array includes detectors with quantum well layers that are spectrally “tuned” to impinging radiation by modulating the voltage biases applied across each quantum well layer. Read out circuits, interfaced with each detector of the array, process the photo-currents received from each detector to determine the absolute temperature of the remote infrared source from which the impinging radiation originated.

Abstract: A method and apparatus to reduce undesirable deficiencies in an image produced by a microbolometer array including multiple smaller arrays includes applying a separate bias pulse to each of the microbolometers in the smaller arrays and measuring a resulting signal corresponding to the applied bias pulse for each of the microbolometers using multiple measurement circuits associated with the smaller arrays during the frame time. Further, one or more known bias pulses are applied to the measurement circuitry during the frame time, one or more resulting calibration signals are measured, an offset parameter for each of the smaller arrays based on the corresponding measured resulting calibration signals is computed, and the measured resulting signal is corrected using the associated computed offset parameter to produce an output signal that reduces the undesirable deficiencies in the image produced by the array.
