Summary: | 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.
