The InGaAs focal plane array detector with the type of FPA-320x256-C was selected as the core component of the diffraction grating laser warning device. The detection theory of laser wavelen

Fusion of Dual Color MWIR Images Based on Support Value Transform and top-hat Decomposition
Su-zhen LIN, Feng-bao YANG, and Lei CHEN
Fusion method of dual color mid-wave infrared images is presented in this paper in order to solve such frequently rising issues as limited contrast ratio improvement and serious marginal area distortion in the fusion of the above two images using multi-scale top-hat decomposition. The detailed procedure is shown as the
