Abstract
An apparatus and method for viewing a scene where a portion of the field of view may exhibit excessive brightness, comprising a nonlinear optical scattering screen for which the scattering coefficient of the screen decreases rapidly with increasing light intensity above a threshold intensity. The scene is viewed by imaging light from the scene onto the nonlinear scattering screen and then reimaging the light scattered by the screen onto human retinas or other light detectors.
