The temporally selective view diffuser is a system that allows an optical instrument or a person using special viewing apparatus (handheld device, special eyeglasses, special contact lens, or the like) to view through a surface that appears to other people as if it were a diffuse or opaque surface. The invention allows optical instruments such as optical motion detectors, optical flow detectors, presence detectors that require a nonscattered view, imaging systems, etc., to be concealed behind an apparently opaque or diffuse surface having the appearance of a white or coloured ceramic tile, white or coloured vitreous china, or the like.
