Thermal imaging cameras based on infrared focal plane arrays (IR FPA) are
increasingly used for day/night electro-optical observation systems. Thermal images
captured by such cameras are generally degraded by fixed pattern noises (FPN). The
most used Non-Uniformity Correction (NUC) technique to minimize the influence of
FPN and improve the infrared image quality of thermal cameras is the linear
calibration using the radiation sources such as blackbody simulators.
The image NUC should be implemented regularly or instantly in field
conditions when required. The blackbody simulators for this purpose are not popular
and generally customized by specific needs. Thus, the topic “Study on design and
fabrication of blackbody simulator for image non-uniformity correction of long-wave
infrared (8-12 m) thermal cameras” is chosen and performed in this thesis to
contribute an effort in solving such practical need. It is a new problem in the research
and development activity of Vietnam.
Purpose of thesis is to research on the efficient calculation methods and the
computational tools usable for designing and fabricating the compact and portable
blackbody simulator based on cylindrical-inner-cone cavity for NUC te
