Optics: Super vision

Optics of aberroscopy and super vision.

This paper (1) reviews the fundamental limits to visual performance imposed by optical imaging and photoreceptor sampling to determine the limits to the potential gains offered by ideal corrections; (2) examines the predicted losses in vision induced by chromatic aberration, phase shifts, typical ocular aberrations, and the gains possible by correcting the monochromatic aberrations of the eye; ...

Vision metrology with super wide angle and fish-eye optics

Photogrammetrists have generally made use of wide or super wide angle rectilinear lenses that are designed to reproduce straight lines in the object space as straight lines in the image space. This paper investigates the use of fish-eye optics as an alternative to the conventional super wide-angle lens for vision metrology. The fish-eye design, whilst still retro-focus in construction, rejects ...

Telecentric Optics for Computational Vision

An optical approach to constant-magniication imaging is described. Magniication variations due to changes in focus setting pose problems for pertinent vision techniques, such as, depth from defocus. It is shown that magniication of a conventional lens can be made invariant to defocus by simply adding an aperture at an analytically derived location. The resulting optical connguration is called \...

Adaptive optics for peripheral vision

Understanding peripheral optical errors and their impact on vision is important for various applications, e.g. research on myopia development and optical correction of patients with central visual field loss. In this study, we investigated whether correction of higher order aberrations with adaptive optics (AO) improve resolution beyond what is achieved with best peripheral refractive correctio...
