摘要： Device converts an analogue signal representing charges resulting from the photo-detection of electromagnetic radiation into a digital signal. Device includes (a) a number of photo-detectors connected in rows and columns through of buses, the photo-detectors in one column sharing the same column bus, itself connected to an output stage by through a row bus, and between each photo-detector and the column bus, (b) an integrator, to integrate the charges arriving from the photo-detector, (c) means for resetting the integrator, and (d) a comparator to compare the voltage Vp from the integrator with an internally predefined threshold voltage Vs, characterized in that it also includes a processing device, a clock, the clock controlling the processing device and the processing device receiving a binary value present at the output of the comparator at each signal from the clock.

摘要： A device for generating an image from an IR radiation including a plurality of polarized heat detectors (2) having specific electric resistances distributed over the focal plane of a detection module so as to deliver a signal representing a detected IR radiation. A read module (8) converts the electric signal into a signal usable by an image processing block (18). An electric signal compensation module (10) having a first branch (12) for obtaining a first thresholding to extract a first constant value signal due to the polarization of the heat detectors. The compensation module (10) includes a second branch (30) for obtaining a second thresholding to extract from the first thresholding signal a second low-level signal due to the dispersion of the electric resistances of the heat detectors and/or to the fluctuations in the temperature of the focal plane of the detection module.
