Image Quality Improvement in Single Pixel IR-Imaging

We have implemented a single-pixel passive imaging system to be used in the infrared range of radiation. The output of the proposed system is under the influence of several disturbing factors. We identified these factors, and modelled their associated noise and distortions theoretically based on which we reduced the effects of these perturbations in the experiment. We described the effect of the thermal noise by covering the system. Also, the size of the aperture was decreased such that only the first order of diffracted wave was received by the sensor. And finally, we used image processing techniques to improve the quality of the image.
