Abstract
To produce the most pleasing display of the color patterns, the colored light, which is produced by interference of light waves from the two surfaces of a thin liquid film, is separated from the principal beam of the incident light, magnified, and projected onto a screen. Reflection from the thin liquid film is specular reflection (angle of reflection equals angle of incidence). The position of the projection lens is determined by the position of the light source. Thin liquid films, such as soap bubbles, reflect colored light by interference of light waves which reflect from the front and back surfaces of the films. The color of the light is a function of the thickness of the film.
Claims6
A dynamic color pattern generator which continually produces colored light patterns reflected from the two surfaces of a thin liquid film and displayed upon a screen comprising:
- a. a light source means positioned within a first container, and directed at the thin liquid film,
- b. means for continually forming the thin liquid film supported by surface tension within a loop-like structure, and enclosed in a second air-sealed container positioned inside first container, and
- c. means for projecting the colored light patterns which are reflected from the said two surfaces of the thin liquid film onto the said screen.
