  • Exponential model based uncooled infrared focal plane array readout circuit
    Patent number: 10996107
    Abstract: The present disclosure relates to an exponential model based uncooled infrared focal plane array readout circuit, including: a first microbolometer unit and a second microbolometer unit, for obtaining a detection signal and a reference signal; a conversion unit, connected with the first and second microbolometer units, and configured for converting the detection signal and reference signal to obtain a linear detection signal and linear reference signal; a subtraction unit, connected with the conversion unit, and configured for calculating a difference between the detection signal and the reference ratio signal to obtain a difference signal; and an integration unit, connected to the subtraction unit, and configured for integrating the difference signal to obtain an electrical signal for characterizing the infrared light signal of the to-be-detected object.
