| Title: |
Visible Light Modifier and Method |
| Abstract: |
A visible light modifier and method provide a new visual display. A
projection is generated by the visible light modifier that includes a
monochromatic or chromatically separated light beam having variations
generating a stunning visual display. The display may be used in
advertising, entertainment, psychotherapy and anywhere that
attention-getting or mood-altering visual displays are desired. The
visible light modifier includes a fluid refractive medium within a
container and a a mirror positioned within the fluid refracting medium at
a predetermined angle so that for multi-chromatic sources an angular
chromatic separation is achieved in a beam reflected from the reflective
surface through the refractive medium, or for monochromatic sources, a
projected beam having a shape variance is achieved. Motion of the fluid
generates variations in the shape and/or chromatic distribution within the
reflected beam, which can be projected on a screen or other suitable
background.
