Non-Linear Optical Materials and Applications

Nonlinear optical (NLO) materials have long been known to interact with light, to produce a nonlinear response. Nonlinear optical materials use nonlinear dependence of the refraction index on the applied electric field to produce other frequencies. This results in either harmonic generation or frequency shifting. The development of the field was …

DARPA MuS2 developing Muon Source to detect shielded nuclear contraband, to objects deeply buried up to thousands of meters below the earth’s surface

Muons are subatomic particles that behave a lot like electrons but are around 200 times heavier. As the US Department of Energy explains, “Muons created in the atmosphere constantly hit every inch of the Earth’s surface and pass through almost any substance.”   Many scientists have noted that measuring the …

DARPA developed Battlefield Illusion for deception Electro-Optical Warfare

Magicians and generals have had a long-standing relationship – one that produced very real effects during wartime. Harry Houdini snooped on the German and the Russian militaries for Scotland Yard. English illusionist Jasper Maskelyne is reported to have created dummy submarines and fake tanks to distract Rommel’s army during World …

High Resolution Quantum enhanced LIDAR technology can detect Stealth Aircrafts

Quantum technology (QT) applies quantum mechanical properties such as quantum entanglement, quantum superposition, and No-cloning theorem to quantum systems such as atoms, ions, electrons, photons, or molecules. Quantum bit is the basic unit of quantum information.  Whereas in a classical system, a bit is either in one state or the another. …

3D camera technology for computer vision and Metaverse Applications

A regular (non 3D) camera records images either as a still photograph or as moving images known as videos or movies, which in turn are stored in a physical medium such as in a digital system or on photographic film. A camera comprises a lens which focuses light from the …

Biggest Land and Space telescopes in optical, infrared and Radio of the world

A telescope is an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, or various devices used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation.   Optical telescopes are used for astronomy and in many non-astronomical instruments, including: theodolites …

3-D hologram technology advancing to Real-Time 3D Holograms on a Smartphone

We see things because our eyes are sophisticated light detectors: they constantly capture the light rays bouncing off nearby objects so our brain can construct an ever-changing impression of the world around us. When our eyes see a three-dimensional image such as apple, Light reflects off the surface of the apple …

Electro-Optical /infrared (EO/IR) systems on Military airborne, land-based, and naval platforms systems

Electro optics is a subfield of electronics and material physics that deals with devices, components, and systems that rely on the transmission and interaction of light with diverse materials. Electro-optical or EO systems refer to devices that make use of a mix of optics and electronics for generating, detecting and …

Programmable Photonic Chips to be deployed in more diverse applications

Photonics is a breakthrough technology as it uses photons (smallest unit of light) as the data carrier instead of electrons (smallest unit of electricity) used in electronic ICs. As light travels at very high speeds, photonics is widely used to transfer huge amounts of data at a very high speed.Thus …
