Rainbow phenomenon based on theories of color vision
To study the visual characteristics of rainbow and the influence of refractive media on it,a replication plan for the rainbow in the laboratory was designed.With the theory of color vision,chromaticity diagrams could quantitatively characterize the imaging quality.A replication plan based on liquid media was designed to obtain a bow-shaped chromaticity diagram that conformed to theoreti-cal deductions,verifying the feasibility of the above method.A replication plan based on acrylic mate-rials was designed to obtain the rainbow and its corresponding chromaticity diagrams for refractive ma-terials with different particle sizes and uniformity degrees.As the particle size of the medium in-creased,the richness of colors in the corresponding rainbow improved significantly.Mixing refractive media with different particle sizes and making them uniformly distributed could result in a more color-ful rainbow.Through multiple experiments,it was found that when 0.1～0.2 mm and 0.2～0.4 mm acrylic spheres were mixed at a ratio of 5∶12,the resulting rainbow has the distinct strip distribu-tion,high color richness,and low noise ratio.
