Research and design of single lens high resolution imaging system

Single convex lens can image objects outside of the focus length, there are a variety of problems, such as different forms of aberration and low resolution. The larger the aperture is, the lower full field MTF is. Multiple lenses are used to correct aberration. The liquid crystal spatial light modulator and micro scanning optical wedge were proposed to realize high resolution imaging with the single lens. It is suggested to use Zygo interferometer to measure single lens with Zemax software simulation wavefront, the Zernike polynomials was applied to describe the distortional wavefront, the conjugate grayscale map was drawn to load in the liquid crystal spatial light modulator and calibrated wave aberration. The optical wedge of 21 was rotated to complete 22 micro scanning. Four low resolution images, through Keren registration and structure-adaptive normalized convolution algorithm, ultimately were synthesized into a high resolution image. The image resolution is promoted to 1 348 LW/PH at MTF50, which proves its effectiveness.
