Abstract

Previously, it was demonstrated that radial basis functions may be preferred as a free-form shape descriptor for a single-mirror magnifier, justified by a performance increase measured by the MTF, when compared to other conventional descriptions such as multivariate polynomials (e.g., Zernike polynomials or x-y polynomials). The benefit in performance increase can be used to expand the pupil diameter from 8 to 12 mm given a 20° field of view and a 15-mm eye clearance or to increase the field of view. The main contribution in this paper is the investigation of the field-of-view limit in a dual-element magnifier where the free-form mirror is described with radial basis functions. Our main result in this paper is an estimate of the field-of-view limit of the dual-element magnifier to be approximately 25° full-field diagonal, given the specific geometry described in the paper. The impact of the astigmatic node placement in a rectangular image field on the modulation transfer function is also analyzed for the particular dual-element magnifier geometry. © Copyright 2008 Society for Information Display.
