Abstract

With new thermal imaging technologies emerging each day, thermal imaging sensors are showing of a trend of decreasing pitch lengths. In this paper, the statistical advantages of using different pixel pitch sizes for LWIR uncooled thermal imaging sensors are investigated. Comparisons are made between 12um and 17um pitch sizes and the results are evaluated using the Johnson criteria, PSNR, MSE and observatory methods. It is found that 12um pitch sizes give better results in terms of both the statistical methods and observatory methods. Edge sharpness and PSNR values are also increased.
