Mid-Infrared Upconversion Imaging Under Different Illumination Conditions
Zheng Ge, Zhao-Qi-Zhi Han, Yi-Yang Liu +9
Converting the medium infrared field to the visible band is an effective image detection method. We propose a comprehensive theory of image up-conversion under continuous optical p…

Thermal camera based on frequency upconversion and its noise-equivalent temperature difference characterization
Zheng Ge, Zhi-Yuan Zhou, Jing-Xin Ceng +5
We present a scheme for estimating the noise-equivalent temperature difference (NETD) of frequency upconversion detectors (UCDs) that detect mid-infrared (MIR) light. In particular…
