POLYCHROMATIC CONSIDERATIONS FOR THE COMPENSATION OF THE WAVEFRONT ABERRATION OF THE HUMAN EYE

摘要

In this paper, we describe a polychromatic approach for enhancing text for users with visual aberrations on an LCD panel that has been chromatically characterized. This research is based on a priori knowledge of the user's visual aberration, as measured by a wavefront analyzer, as well as the knowledge that the PSF of the human eye will change depending on the source wavelength. Leveraging on the chromatic characterization of the LCD panel, it is possible to generate text that, when displayed to a user, will counteract his/her visual aberration in way that improves optical visual function. The method described in this paper advances the development of techniques for providing such compensation by integrating chromatic information of the visual system a means to enhance the display of precompensated text.
