Providing a homogeneous visual field with an integrating sphere.
Homogeneous visual fields are widely used in visual perception and psychophysical studies. An integrating sphere can be guaranteed to provide a homogeneous diffuse source of illumination. We report here on a custom built integrating sphere, which provides a uniformly illuminated, unpatterned visual field. The apparatus allows for superior subject comfort over other methods. Binocular viewing is facilitated and the apparatus is highly adaptable to various experimental situations requiring a homogeneous visual field.
