Polarization modeling by means of the Mueller matrix formalism is widely used for representation and optimization of the performance of complex polarization-sensitive systems. Yet, this turns out to be a challenge, as soon as such systems become dyna

Abstract Background Reliable detection of central fixation and eye alignment is essential in the diagnosis of amblyopia (“lazy eye”), which can lead to blindness. Our lab has developed and reported earlier a pediatric vision screener that perform

To investigate whether detection of disconjugacy of eye movements during attempted fixation, or interocular position instability, may serve as a single sensitive test for amblyopia.Binocular eye movements were recorded at 500 Hz using the EyeLink 100

Many diagnostic and some therapeutic ophthalmic devices require a reliable complementing method to track the direction of gaze or just to validate fixation of the eye on a presented target. This would allow acquisition of artefact-free robust images

Newer methods for treating amblyopia use shutter glasses to occlude the strong eye.Needed is a computer-based system to perform liquid crystal shuttering in laboratory and clinical settings, possibly also for home use.In order to achieve good timing

Polarised near-infra-red light is reflected from the foveal area in a detectable bow-tie pattern of polarisation states, offering the opportunity for eye tracking. A coaxial optical transducer was developed, consisting of a laser diode, a polariser,

This study relates to eye fixation systems with combined optical and audio systems. Many devices for eye diagnostics and some devices for eye therapeutics require the patient to fixate on a small target for a certain period of time, during which the

In a polarization-sensitive optical system, it is important to understand the effects that mirrors have on polarization at a specific wavelength of interest, angle of incidence, reflective material, coating, etc. When modeling reflection, the optical
