After walking on Earth for a few hundred years, humans may think they have seen everything. But not according to a team of scientists who claim to have suffered from a color that no one has seen before.
The bold assertion – and the disputed – follows an experience in which researchers in the United States launched laser pulses in their eyes. By stimulating individual cells in the retina, pushing the laser visualizes it beyond its normal limits.
Their description of the color is not very detention-the five people who saw him call it green blue-but they say, they do not completely rich the experience.
“We expected from the beginning that it looks like an unprecedented colored signal, but we did not know what the brain would do with,” said Berkeley, Rin Ng, an electric engineer at the University of California, Berkeley. “The jaw was in the jaw. It is incredibly saturated.”
The researchers shared a picture of the turquoise box to give a color feeling, which they called Oulu, but they emphasized that the color can only be tried by laser manipulation of the retina.
“There is no way to transfer this color in an article or on a screen,” said Austin Rolada, a team’s vision world. “The basic point is that this is not the color we see, it’s not. The color we see is a version of it, but it completely diminishes compared to the Olo experience.”
Humans see the colors of the world when the light falls on the color sensitive cells called cones in the retina. There are three types of cones sensitive (L), medium (M) and short (S) wavelengths of light.
Natural light is a mixture of multiple wavelengths that stimulate the violations of L, M and S to different domains. Differences are seen as different colors. Red light stimulates primarily the L -cones, while the blue light is spread on the S. But the M conic is sitting in the middle and there is no natural light that raises this alone.
Berkeley team started to overcome the registration. They started drawing maps of a small part of the retina to locate its cone. Then the laser is used to wipe the retina. When it comes to the Met, after seizing the movement of the eye, it releases a small pulse of the light to stimulate the cell, before moving to the next cone.
The result, published in Science progressIt is a piece of color in the field of vision around twice the size of the moon’s completion. The color exceeds the normal range of the naked eye because the M coni is almost exclusively stimulated, the natural light of the state cannot be achieved. The name Olo comes from the duo 010, indicating that it is from the optics L, M and S, the M conic is only turned on.
I left the claim, one confused expert. “It is not a new color,” said John Barbour, a vision scientist in St. George, London University. “It is a more saturated green that can only be produced in a topic with a regular red green color mechanism when the only inputs come from the M.” He said that the work had a “limited value.”
Researchers believe that the tool, named Oz Vision after the city of Emerald in LRANK BAUM books, will help them achieve basic scientific questions on how the brain creates visual perceptions of the world. But it may have other applications. Through the detailed stimulation of cells in the retina, the researchers may learn more about the color of color or diseases that affect vision such as Dygomatic retinal inflammation.
Will the rest of the world have an opportunity to experience Olu for themselves? “This is the primary science,” said NG. “We will not see Olo on any smartphone offers or any TVs anytime soon. This is very far from VR headphone technology.”
