System and method for projecting onto an upper surface of a body of water

摘要

A projection system (100) for projecting light (160) such as images or content upon a liquid surface (122) such as a lake or pool surface. The system includes an agitation assembly (130) selectively operable to agitate a portion (124) of the upper surface (122) of liquid (120) to form a projection screen (124). The system includes a projector assembly (150) projecting or focusing light onto the projection screen (124) on the upper surface (122) of the liquid (120). The liquid is translucent to light, but the projection screen (124) on the upper surface (122) reflects a portion of the projected light due to the agitation. The agitation assembly may include an aeration system (230) with a distribution manifold (236) and is positioned below the liquid surface and has outlets discharging gas into the liquid (220) such that air bubbles for the screen. The manifold outlets may be provided at two or more depths, whereby two or more portions of the projection screen (224) are generated at differing times.
