Invisibility is the state of an object that cannot be seen. An object in this state is said to be invisible (literally, "not visible"). The term is often used in fantasy/science fiction, where objects cannot be seen by magical or technological means; however, its effects can also be demonstrated in the real world, particularly in physics and perceptual psychology classes.
Since objects can be seen by light in the visible spectrum from a source reflecting off their surfaces and hitting the viewer's eye, the most natural form of invisibility (whether real or fictional) is an object that neither reflects nor absorbs light (that is, it allows light to pass through it). This is known as transparency, and is seen in many naturally occurring materials (although no naturally occurring material is 100% transparent).
Invisibility perception depends on several optical and visual factors. For example, invisibility depends on the eyes of the observer and/or the instruments used. Thus an object can be classified as "invisible to" a person, animal, instrument, etc. In research on sensorial perception it has been shown that invisibility is perceived in cycles.
A new cloaking device can make an object invisible across a wide range of angles. How exactly does it work? Amy joins us to discuss.

In science fiction, capes can make kids invisible, but in real life, scientists have only been able to hide certain wavelengths of light — and so far those have been in the part of the spectrum we can’t see." ‘Cloaking’ device uses ordinary lenses to hide objects across range of an...
A solider gets out of his tank after they are hit by an IED. We see the hatch open but no one is seen leaving. Moments later you see the soldier running back to the hatch. His cloaking device seems to be wearing off. Only way to detect these suckers are with motion censors around your house, or thermal imaging. Due to youtube banning me from Adsense & Fan Funding for 6 months I decided to start this fundraiser for those who wish to contribute. Thanks in advance.

Subscribe! http://bit.ly/ACSReactions Have you ever wished you could hide under an invisibility cloak like Harry Potter or conceal your car with a Klingon cloaking device like in Star Trek? In a special bonus episode of Reactions, we celebrate the International Year of Light by exploring the science behind light, sight and invisibility. Though we can’t make ourselves invisible yet, some promising research may light the way – or rather, bend the light away. This episode of Reactions was produced in collaboration with the journal ACS Photonics. For more information on ACS Photonics, please visit: http://pubs.acs.org/journal/apchd5.

Researchers in Japan have invented an incredible invisibility cloak. The technology comes from 2003, but it's developers say the Harry Potter-like invisibility cloak is just the beginning. The team, led by Dr. Susumu Tachi, from Keio University, is now adapting their findings to help pilots, drivers, doctors and others. Retro-reflective projection technology uses a computer, a video camera and projector to shine background images onto the front of a subject wearing specialised clothing, creating the illusion of invisibility. What makes the technology unique is a fabric made of glass beads only 50 microns wide, which can reflect light directly back at the source, much like the screen in a cinema. Viewed from near the light source, the projection is bright even in broad dayligh...
