چکیده

The key contribution is the design, analysis, and fabrication of a dual-element off-axis magnifier to improve the state of the art in catadioptric magnifiers. The catadioptric magnifier is composed of a free-form mirror and a lens with a diffractive optical element. A monocular magnifier was prototyped, to our knowledge for the first time, with the specifications of an 8 mm exit pupil, 20 degrees diagonal full field of view, 15 mm eye clearance, 1.5 arcmin resolution, and operating in the photopic visual regime.

Application of radial basis functions to shape description in a dual-element off-axis magnifier.

We previously demonstrated that radial basis functions may be preferred as a descriptor of free-form shape for a single mirror magnifier when compared to other conventional descriptions such as polynomials [Opt. Express 16, 1583 (2008)]. A key contribution is the application of radial basis functions to describe and optimize the shape of a free-form mirror in a dual-element magnifier with the s...

Dual-element Off-axis Eyeglass-Based Display

Eyeglass-based displays are expected to become a primary visual display option for future wearable computing platforms. There has been several prototypes in the area of eyeglass-based displays. Example of previous designs include the work by Bettinger[1], Spitzer[2] and Kasai[3]. A comprehensive review of designs in the eyeglass formfactor is provided in [4]. In this paper, we explore the possi...

Optimal local shape description for rotationally non-symmetric optical surface design and analysis.

A local optical surface representation as a sum of basis functions is proposed and implemented. Specifically, we investigate the use of linear combination of Gaussians. The proposed approach is a local descriptor of shape and we show how such surfaces are optimized to represent rotationally non-symmetric surfaces as well as rotationally symmetric surfaces. As an optical design example, a single...

Use of three-dimensional ultrasonography of the eye and measurement of optical long axis in dog

This study was conducted to determine the use of three-dimensional ultrasonography (3DU) in ocular imaging of the dog and measuring of its optical axis. 12 healthy mixed-breed dogs including 6 males and 6 females were studied. 3DU of the eyes were done using a 5–12 MHz linear trapezoid transducer. 3DU of the eyes were evaluated and the normal optical long axis through a line between the cornea ...

Assessment of minimum permissible geometrical parameters of a near-to-eye display.

Light weight and small dimensions are some of the most important characteristics of near-to-eye displays (NEDs). These displays consist of two basic parts: a microdisplay for generating an image and supplementary optics in order to see the image. Nowadays, the pixel size of microdisplays may be less than 4 μm, which makes the supplementary optics the major factor in defining restrictions on a N...
