Description
Technical Field
The invention relates to a science popularization demonstration device for identifying similar colors by eyes, which is used for exhibition of optical exhibits in a science and technology center and belongs to the field of optical science popularization education.
Background
The color is formed by irradiating light onto the surface of a colored object, reflecting the light and then injecting the light into human eyes, transmitting information to the brain, combining our life experience with the brain, and processing the information to generate a visual effect on light.
The resolution of color by the human eye is mainly affected by physiological and environmental factors. The physiological factors are the deficiency of the congenital genes, which leads to the human eyes incapable of accurately distinguishing colors, such as achromatopsia and color weakness. There are many influencing factors for environmental factors, such as: 1. the brightness, under the condition that the illumination is sufficient in daytime and the brightness is sufficient, the human eyes can distinguish the different colors; however, at night, the human eyes cannot distinguish colors under the conditions of no illumination and insufficient brightness, and the objects are black and white. 2. The space distance is very similar to that of two colors, if the space distance is far, the human eyes can hardly distinguish the difference of the two colors; if the spatial distance is relatively close, it is easily discernable.
The human eyes recognize similar colors to be very important content in optical research, not only occupy important positions in teaching experiments, but also have knowledge points in most science and technology museums, but the science and popularization demonstration devices in the prior art museums only have two exhibition forms. One is to let the viewer see through different colored optical lenses, experience the optical world in the eyes of achromatopsia and feeble patients, and the phenomenon of viewing in the form of the display term is simple, single and often is a static image. The other is to make the audience find color blocks with similar colors on the computer screen, and see who finds the color blocks accurately, and who uses less time. The exhibition item forms of the two science popularization demonstration devices only aim at part of influence factors of human eyes on color resolution, the coverage range is not comprehensive, and more spectators experience effects, and the science theory of the spectators is not really learned in interaction. Such science popularization presentation device of part science and technology museums is big heavy, is difficult for removing, when meeting activities such as science popularization entering campus, this showpiece has received the restriction because of the volume.
