Abstract

Psychrometric functions were determined concurrently for detection of luminance sinusoidally modulated with a spatial frequency and for luminance modulated by the sum of two sinusoids of differing frequency. Results support the hypothesis that the human visual system contains sensory channels, each selectively sensitive to different narrow range of spatial frequencies whose outputs are detected independently.
