Abstract
A device, a method, and a computer program for producing two point light sources of the same wavelength on a pupil plane of an eye of a user are disclosed, as well as a device, a method, and a computer program for determining a neural transfer function of the visual pathway of the user. The device for determining the neural transfer function includes a coherent light source for generating a light beam; an optical device for separating the light beam into sub-light beams, superpositioning the respective sub-light beams, and adjusting contrast and spatial phase in an interference pattern; and a beam path for guiding the superposed sub-light beams such that two point light sources of the same wavelength are produced. The devices are compact and robust, allow a variable presentation of different interference patterns, and can thus be easily operated in a commercial product in a clinical setting.
