Design And Optimization Of Fish-eye Lens And Zoom Fish-eye Lens

Zoom lens is flourishing with the development of computer technology and precision machinery design. Also all kinds of sensors have found an increasingly wide utilization in zoom lens. Because the horizontal view angle of human eyes is approximately90°, and the vertical view angle is70°. At the same time fish-eye lens possess broader field angle than human eyes have. So the zoom fish-eye lens comes into the world. Which have the superiority of zoom lens; also have the characteristics of fish-eye lens. More and more people apply their mind to research or design of zoom fish-eye lens.The main propose of the paper is to design the systems of super short-focus panoramic fish-eye lens and zoom fish-eye lens. The finished work is shown below:1. The relationship of super short-focus panoramic fish-eye lens’s focus and resolution was studied comprehensively. This is based on the imaging principle of fish-eye lens optical design. Then we lay down the design target of super short-focus panoramic fish-eye lens, and optimize it.2. The zoom lens’s equation of motion is researching. Therefore we draw up the design target of zoom fish-eye lens from the relevant patent, and optimize it.The innovativeness of the paper is shown below:1. The relationship of super short-focus panoramic fish-eye lens’s focus and resolution was studied comprehensively. It is proved that the shorter the focus, the higher the resolution of scenic circle area.2. The super short-focus panoramic fish-eye lens has been designed successfully. Whose ratio of focus and image height is less than0.35. Its structure is simple, and has5million pixels.3. The zoom fish-eye lens has been designed successfully. Whose glasses are all spherical, and has1/6"-2/3" image size.
