Abstract

With the demand on Infrared and Electro-Optical sensors’ detectability, Large aperture optics have been widely used. But the deform of the opto-mechanical system has been induced by heavy deadweight of the large aperture optical elements and by the change of environment temperature could lead to the attenuation of the Infrared and Electro-Optical sensors’ detectability. For weakening the influence of deadweight deform and temperature change, people utilize the fruits of adaptive optical technology achieved the unattenuated performance of Electro-Optical sensors. A infrared adaptive optical system based on Hartmann-Shack wave-front sensor is designed. The wave-front sensor has adopted in the visual spectrum for lower cost and higher precision. So the fore large aperture telescope must work in the dual waveband such as middle-infrared wavelength and visual wavelength. The final dual-waveband telescope achieved 4’ collimation at the visual wavelength and 10’ collimation at the middle-infrared wavelength. The dual-waveband optical system for IR adaptive system achieved high-resolution middle-infrared imaging and real-time visual-waveband wave-front distortion measuring.
