We present results on the design of an optical image forming system. The design will enable us to study small apertures effect in image formation of the eye. The system is designed to operate with various laser sources and to obtain the Modulation transfer function (MTF) dependence with wavelength. It is then extended to characterize the monochromatic MTF function, its spatial dependence on the aperture size of the limited system and the spectral dependence of the optical system response. Computational work is compared with experimental data. © Anita Publications. All rights reserved.
