ABSTRACT
Patient is placed behind holographic plate and is forced to change vergence and accommodation by consequent switching on this two 3D fixation images. For dynamic refraction measurement is used near infrared eccentric video-refraction [3]. Source of near infrared (NIR) beam (Fig. 3) is designed as array (25 × 5 mm) of four NIR light emitting diodes (λ = 850 nm, 80 m W/30°) placed near optical axis of camera’s lens (with respecting of the eccentric photo-refraction conditions).
