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...

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; ...

Applications of Adaptive Optics for Vision Science

There are a number of applications of adaptive optics for basic research in vision science, as it is now possible to study microstructures in the living human retina which could not be done before. One of the biggest merits provided by adaptive optics is that it is non-invasive. In this chapter, we describe the applications of an adaptive optics system for vision research, not only for basic sc...
