Optical Turntable
★Exhibit Content: Persistence of vision, color light mixing principle, science popularization of visual imaging of light ★Interaction: Manual interaction ★Operation: Drive the turntable through the hand-crank mechanism, observe the changes in patterns and colors at different speeds, and experience the magical effects of persistence of vision and color light mixing. ★Exhibit Description: The exhibit consists of a cold-rolled steel plate platform main body, stainless steel bearing shaft, multiple sets of optical turntables with different patterns, hand-crank drive handle, instruction sign, etc. It is a recommended exhibit for the PopsciCat Exhibit Store. Visitors can hand-crank the turntable to observe the dynamic visual changes of static patterns at different speeds, and intuitively understand the optical principles of persistence of vision and color light mixing. ★Scientific Principle: This exhibit is based on the persistence of vision phenomenon of the human eye and the principle of color light mixing: Persistence of vision: The human eye can retain the impression of light stimulation for about 0.1 seconds, causing rapidly rotating static patterns to merge into a continuous dynamic effect in the brain; Color light mixing: After light of different wavelengths is mixed, the human eye perceives a new color. When the turntable rotates at high speed, different color blocks mix in vision, presenting color and pattern changes that cannot be observed when static; This is a classic visual optics science popularization exhibit, intuitively demonstrating the impact of persistence of vision on color perception.
