博士 === 國立中央大學 === 光電(科學)研究所 === 84 === A method was developed for solving zoom lens layout. The number moving component is not limited by using this method. The damped least squares method is used for finding the solution of zoom lens and the polynomial equations are used for zoom run during the optimization process. Several constraints are also used for smoothing and minimizing the sensitivity of the system. The solution areas of the three-component afocal zoom system with two moving components are solved. There are totally eight areas which are found by this analytical method. This paper discusses a generalized two-component homotopic zoom system, in which both refractive and reflective systems are The solution areas of refractive and reflective homotopic are classified. The technique for stable aberration correction of zoom systems is described. The position of the zoom is designated the reference position, and the primary aberrations including the spherical aberration and longitudinal chromatic aberration of the pupil, of each component are used as independent variables. The values of these needed for stable correction of the primary aberrations are determined, and the different components are then designed. Two zoom systems are designed in the final section of this paper to witness the total solution of designing a zoom system. The is a 35mm telephoto camera zoom system. The second design is a thermal imager with 4 zooming components.
