Invisibility Is Not Magic, And Scientists Have Made Use Of Optical Lenses.

- Jul 10, 2017-

Most stealth technologies now require unique tools and technologies, such as fiber optics and super materials. But the finished product is not very practical, and the stealth effect will be lost when moving. The University of Rochester in the United States has proposed a more practical approach to invisibility by using polished optical lenses to refract the light and create an illusion of invisibility. To be quite frankly, this method is actually a clever optical solution. By placing two sets of lenses on a particular bit of realty, the researchers can "twist" the light through the middle to bypass the object, looking like objects become invisible. This method can be used to use larger lenses to hide larger objects, and the effective angle is more than 15 degrees; the viewer is not limited to a certain angle to appreciate the stealth effect.

This "stealth system" has a fairly useful application. It cannot be invisible to the central object, so it seems to be used only in the midst of seeing objects more completely disguised. But the system can be used to reduce the blind spot of a vehicle, or to allow surgeons to "see through" their hands during surgery. Although the device is still in the early stages of research, it is a long time away from practical application, but its simplicity brings more possibilities.
