MRTD: to NUC or not to NUC?
(2020-09-21)
We applied a simple method to estimate the Minimum Resolvable Temperature Difference (MRTD) of an LWIR and an MWIR camera. A so-called Siemens star, in our case a thin, black aluminum plate framing a circle that is missing ...
Three-dimensional signal decomposition of infrared image sequences and large-scale non-uniformity analysis
(2020-09-20)
The three-dimensional noise model is a methodology to analyse the noise of a thermal imaging sensor, such as an infrared (IR) camera. This allows us to decompose a noisy signal into components and quantify properties such ...
Detection: how many pixels are required?
(2020-09-23)
In this work, we studied how detection range of a small target changes as a function of the number of defined target pixels. The intuitively simplest method to look for a target in IR images is to look for the “hottest” ...
