Visual System Modeling: Putting the Pieces Together

Studying the optical performance of the human eye is a central problem in physiological optics. In recent years, the topic has received increasing attention because of the potential applications in ophthalmic optics. The double pass (or ophthalmoscopic) technique has been used over the last 40 years as an objective method to estimate ocular image quality. It records the light reflected back in the retina when the eye forms an image of an object test. This external retinal image (aerial image) is used to estimate aberrations of the eye, point and line spread functions, and the ocular modulation transfer function (MTF).
