A foam particulate projection system is disclosed. The proposed system consists of a foam generator, an air knife (which is optional) and a device for collecting the foam (a collection device). The foam generator is suspended from a certain height depending on the size of the required particulate foam screen. The foam that is generated is channeled by the air knife which consists of a high intensity, uniform sheet of laminar airflow. The resulting foam screen acts as a display screen on theme park rides as shown. Further a projector is deployed for projecting an image onto the foam screen.
The present technique relates generally to projection systems, and more specifically to a foam particulate projection system.
Projection systems are widely used to display movies, presentations or any other visual images. It generally consists of a screen or any flat surface and a projector. Digital 3-D (three dimensional), LCD( Liquid Crystal Display) screens, overhead projectors, magic lantern, slide projectors are some of the technologies available today in projection systems.
There exist various non-traditional media which are used as projection screens, such as water droplets, mist (fog), and fire which are used to create two and three dimensional displays. These types of screens find applications in display shows, such as water dome, aquatique show and disney’s fantasmic show. Spray sheets of freely flowing or high-velocity water are used to create impressive displays. Typically during rides in theme parks, designers would like to provide projected effects in areas where it might not be possible to install screen. By utilizing a safe particulate made screen these effects may be realized.
Various conventional techniques, such as fog projection systems have been used for art and entertainment purposes, but the rapid dispersion of the fog seriously limits the fidelity of projected images. The dispersion is caused by turbulence and friction in the fog’s flow, which disrupts the desired smooth planar surface, causing projected points of light to streak into lines. This streaking causes severe distortion of the image when viewed from certain angles. In other conventional techniques for producing particulate screens, the magnitude and wetness of these screens, as well as their large water consumption, make them impractical for indoor or small-scale applications. Further such conventional techniques also preclude the viewers from comfortably passing through the display space and seeing clear images from short distances.
Therefore there exists a need for a foam particulate projection system that overcomes the above cited limitations.
