Abstract

The feasibility of the imaging reconstruction in the infrared domain according to the basic reconstruction method of Zernike moment in the visible range, is discussed. Due to the orthogonality of Zernike polynomials, any image within an unit circle can be represented by Zernike moments. Therefore, we propose an approach to reconstruct the target images inside the unit circle in the infrared wavelength range. Firstly, according to the light intensity distribution of the infrared object selected, a relatively clear image can be successfully reconstructed based on the Zernike moment reconstruction. And then according to the liquid-crystal Shaker-Hartmann wavefront measurement technology, the phase distribution corresponding to a tailored incident wavefront of the target radiation can be successfully recovered according to the refocusing spots of the liquid-crystal micro lenses over the CCD. Through combining wavefront measurement and recovery and further the infrared image reconstruction of the target, both the theoretical basis and the algorithm for recovering wavefront according to the intensity distribution of the infrared image are provided.
