    Abstract

    The Q-type novel aspherical polynomials and its advantages are introduced in the aspect of algorithm, fabrication and manufacturing relative to the traditional aspherical polynomial-based aspheres. The Q-type formulation is applied to design a panoramic lens based on the relationship of super short-focus panoramic lens′ focus and resolution. The designed panoramic lens′ focus is 0.657 mm and ratio of focus and image height is less than 0.184, which includes 4 aspheric surface. This result shows that the spatial pixel of scenic circle area with half vertical field 45°~90° is up to 1.163 7 mm/(°), and the modulation transformation function is greater than 0.3 at the spatial frequency of 227 lp/mm. The result demonstrates the Q-type formulations is certain advantages in super short-focus panoramic lens.
