Integrated airborne night vision goggle is a typical and very complex airborne optical system. This paper discusses the fundamental idea and main strategy of wide wave range multi sensor integrated optical system. In optimized design, damped least squares method and adaptive procedure are used to get higher relative aperture, lower distortion and appropriate MTF, and so on. Calculation results and aberration evaluation on objective system, equivalent eyepiece system, CRT imaging system and CCD display system are reported. Key problems are discussed and summarized.
