Paper Abstract

In the special case of optics for video discs we present an optical imaging system which is capable of giving the high resolution required for polychromatic radiation from a laser diode and an extended object field. A combination of an in-line holographic lens and a glass lens with a small coma, a small chromatic aberration and a very small spherical aberration giving almost diffraction-limited imaging over a relatively large object field and a relatively large spectral bandwidth, is here proposed and analyzed. Optimization programs yielded highly corrected imaging systems by comparably simple holographic means. The use of only two surfaces results in very compact and lightweight systems, the image quality of which is described for monochromatic and polychromatic illumination by means of optical transfer functions and wave aberrations.
