摘要： A light-emitting diode array is driven by a digital control. The digital control modulates the pulse width of pulses applied to the light-emitting diode. The intensity of the output is controlled by controlling the width of pulses applied to the light-emitting diode. Since light-emitting diodes have very low inertial energy, this system can be rapidly turned on and turned off. The output is integrated to produce a uniform output.

摘要： A thermal imaging system (10) which is accoupled and by scanning recreates a thermal image by superimposing measured variations in infrared emission from a scene (22) onto a reference level supplied by a light emitting diode (28). The diode (28) is both a positive and negative luminescent emitter. Emitted flux is current controlled to be equivalent to black body radiation at a range of temperatures which may be colder or hotter than ambient. A signal generated with the system (10) switches between scene and diode observation is a measure of the difference between the mean scene temperature and the diode effective temperature. In response to this digital, control means adjust the bias current through the diode (28) in order to reduce the temperature difference. The reference temperature converges towards the mean scene temperature as this process is repeated. Absolute temperature is thus restored and some image defects removed.

摘要： An offset corrector for a focal plane array. A bolometer array configured in a row and column readout format has dedicated column circuits to measure the resistance of each bolometer in the column. A high speed on-chip analog to digital converter converts the analog sensor signal to a digital representation. Since the response of each bolometer varies, an offset controller, connected to the output of the analog to digital converter, corrects the digital representation for variations in individual bolometer response. Each pixel has a corresponding dynamically computed offset stored in the memory. The offset is computed when a chopper or shutter blocks radiation from the focal plane array. The focal plane array is temperature stabilized to a predetermined temperature to keep bolometer response within a predetermined bandwidth.
