Description
Technical Field
The invention relates to a science popularization demonstration device for identifying similar colors by human eyes, which is used for showing optical exhibits in science and technology museums and belongs to the field of optical science popularization education.
Background
The color is formed by irradiating light on the surface of a colored object, reflecting the light and then emitting the light to human eyes, and then transmitting information to the brain, wherein the brain combines the life experience of people and processes the information to generate a visual effect on the light.
The human eye's resolution of color is mainly influenced by physiological and environmental factors. Among them, the physiological factors are that human eyes cannot accurately distinguish colors, such as achromatopsia and color weakness, due to the deficiency of innate genes. Environmental factors have many factors, such as: 1. the brightness is enough in the daytime, and under the condition that the brightness is enough, human eyes can distinguish different colors; however, at night, under the conditions of no illumination and insufficient brightness, human eyes cannot distinguish colors, and objects seen by the human eyes are both black and white. 2. The spatial distance is two very similar colors, and if the spatial distance is far, the human eyes can hardly distinguish the difference; if the space distance is short, the resolution is easy.
The human eye identification of similar colors is very important in optical research, and not only occupies an important position in teaching experiments, but also is a necessary knowledge point of most science museums, but the popular science demonstration devices of the prior art museums only have two exhibition forms. One is to let the viewer experience the optical world in the eyes of the patient with color blindness and color weakness through the optical lenses with different colors, and the phenomenon viewed by the exhibition form is simple and single, and is often a static image. The other is to let the audience find the color blocks with close colors on the computer screen, and to see who finds it accurately, and who uses less time. The exhibition form of the two science popularization demonstration devices is only explained aiming at a part of the influence factors of human eyes on color resolution, the coverage range is not comprehensive, more is the experience effect of audiences, and the scientific theory is not really learned in interaction. Some science popularization demonstration devices in science and technology museums are large, heavy and not easy to move, and if the science popularization is carried out in activities such as campuses, the exhibit is limited in size. And a few science and technology museums introduce influence factors of human eyes on color resolution to the public only in a text and picture mode.
The prior science popularization demonstration device has incomplete scientific principle coverage, dull and hard explanation modes of characters and pictures and lack of attraction, and is not beneficial to the public to understand and master the influence factors of human eyes on color resolution. At present, a science popularization demonstration device with interestingness, interactivity, mobility and scientificity for identifying similar colors by human eyes is urgently needed, is suitable for being used in science and technology museums or movable science popularization caravans, and is used for popularizing influence factors of human eyes on color resolution.
